Camfil Farr’s new mobile lab and

exhibition is now wheeling around

highways and major cities

in Central and Southern

Europe, the British Isles

and Scandinavia. The trailer

truck could be in your area

right now, and if you haven’t

seen it yet, it will be hard

to miss when you do. This

unique 16-metre-long “roll-

ing exhibit” is an impressive

sight. The message displayed

on the trailer is even more

striking. It boldly asks if clean

air should be a human right.

Do people have a right

to clean air? We think so.

Clean air is one of the

most essential prod-

ucts on the planet and

we deliver it all over the world, along with value to

our customers.

The new mobile exhibition – described inside

and on our website – is one way to raise market

and public awareness about the importance of

clean air and high indoor air quality. We launched

the campaign “at home” in Europe, but the message

is global and relevant to all human beings. Keep in

mind that we breathe around 25,000 litres (6,600

gallons) of air a day and we should be as careful

about our air as our food and drink.

Clean air for life

Several articles in this issue touch upon air pollution

and how it causes harm to humans and impacts the

air we breathe indoors. In the months to come we

will be talking even more about the importance of

clean air, demonstrating how to get it, and explain-

ing the benefits for people, policy-makers and

industry alike. The new mobile exhibition will help us

reach and educate people for this purpose.

Clean air for life starts with good ventilation

and effective and sustainable filtration solutions. It

continues with public awareness of key steps that

can be taken to maintain a healthy indoor environ-

ment and prevent exposure to air pollutants. When

filtration gives us better control over the indoor

environment of our homes, offices, hotels, shop-

ping centres, schools, and other buildings, we are

healthier, feel better and perform more effectively.

Clean air for health, well-being and productivity

– this is our goal.

Pleasant reading!

The dangers of air pollutionThe case for taking stronger measures

to reduce air pollution is becoming

clearer everyday as the media and

the medical community spell out the

dangers of exposure to air pollution.

Pollutants such as airborne particu-

late matter and ground-level ozone

are increasing mortality and hospital

admissions due to respiratory and

cardiovascular disease.

Scientists also say that air pollution triggers

more heart attacks than using cocaine and

poses the same high risk of sparking a heart

attack as alcohol, coffee and physical exer-

tion. Findings also suggest that population-wide

factors like polluted air should be taken more

seriously when looking at heart risks.

Exposure to traffic poses one of the highest

risks since it has the greatest population effect

as more people are exposed to it. Los Angeles

is an example. Here, doctors are studying

asthma and other breathing problems that can

plague American teens living and learning near

the city’s vast network of freeways – problems

that can follow them throughout life and affect

their lung growth.

Even healthy people can develop arrhyth-

mias with acute exposure to air pollution, par-

ticularly fine particulate matter – tiny airborne

grains that can be drawn deeply into the lungs.

Three recent reports

A recent editorial in “The Lancet”, titled “A

breath of fresh air please”, stated that “regu-

latory efforts to curb air pollution on a local,

domestic, and global scale need to be rigor-

ously implemented, enforced, and enhanced.

Governments, as public servants, have the

duty and responsibility to protect the health of

their citizens.” The editorial cites three reports

released earlier this year that underscore “the

importance of having an effective air-pollution

policy for the benefit of health.”

U.S. EPA

The first is the “The Benefits and Costs of the

Clear Air Act from 1990 to 2020”, released

by the US Environmental Protection Authority

(EPA). This report shows that the health ben-

efits greatly exceed the costs of implementing

clean-air protection by quantifying the number

of health-related events preventable as a result

of the Act. The numbers estimated for the year

2020 are dramatic: not only will existing regula-

tions save USD 2 trillion (about EUR 1.4 trillion)

in health costs; it is also estimated that they will

save about 230,000 lives and prevent 200,000

heart attacks, 2.4 million asthma attacks, and

17 million lost working days.

Aphekom

The second report is the three-year Aphekom

research study that was sponsored by the

European Commission and coordinated by the

French Institute of Public Health Surveillance.

In the project, air pollution was surveyed in 25

cities in 12 EU countries, where 39 million peo-

ple live. Curbing air pollution in European cities

could save 19,000 lives per year, add almost

two years to local life expectancy and save EUR

31.5 billion (USD 43.4 billion) in health costs

and work absenteeism, according to the probe.

Particle-value limits are already being

exceeded in various EU member states and

a scheduled revision of present regulations in

2013 is considered a welcome act.

Of all the cities studied, Stockholm was the

only one found to be below the World Health

Organization’s (WHO) recommended level of fine

particulate pollution (10μg/m3).>>>

a i rmai l

Hasselt University

The third is an analysis of 36 studies performed

by Hasselt University in Belgium showing that

air pollution is also an important trigger for

heart attacks. On an individual level, the effect

of air pollution is small (5%), but at the popula-

tion level, air pollution is an important factor in

initiating heart attach triggers, such as physical

exertion, alcohol and coffee.

Killing several million

On a global scale, WHO estimates that at least

2 million people suffer premature deaths globally

each year because of the health effects caused

by a lack of clean air. These deaths vary from

region to region. In Asia alone, for example, a

report published last year found that air pollution

in many Asian cities exceeds WHO’s air quality

guidelines and that toxic cocktails of pollutants

cause 530,000 premature deaths a year.

Outdoor becomes indoor

air pollution

Our industrialized world changed a lot of things

for the human population. Increased pollution

was one change that affected our environment.

Today, air pollution is a global problem whose

seriousness varies from place to place. Since

most of its impacts on human health are long-

term, the problem is often overlooked.

This outdoor pollution, which seeps into our

homes and buildings, can easily contribute to

indoor pollution.

Efficient filtration solutions exist to clean air and

protect people but few are aware of the benefits

of clean air for productivity or controlling costs.

Protecting people from the health impact of air

pollution costs money, but it is also a long-term

investment that can reduce the cost of higher

sick leave rates at workplaces and associated

medical expenses, as well as boost workplace

productivity, as documented in studies.

Our right to clean air

At Camfil Farr we believe there is a need to

increase general awareness of air pollution and

to put Indoor Air Quality (IAQ) on the political

agenda. IAQ should be a public health concern.

For example, vulnerable individuals who live

near roads, where air pollution from traffic is a

serious health risk, should fight for their right to

breathe cleaner air. Doctors could be their vocal

allies in this struggle.

We need to pay attention to the importance

of healthy IAQ. Camfil Farr’s vision is clear: clean

air should be considered a human right.

A few years ago, Sleepyhead (Auckland, New

Zealand), a leader in bed manufacturing and bed-

ding technology, installed a large Camfil Farr carbon

filter to remove all traces of the toxic gas toluene

di-isocyanate (TDI) from the company’s brand-new

polyurethane foam production factory.

In 2010, Sleepyhead built a second foam manu-

facturing plant in Melbourne, Australia, and again

turned to Camfil Farr for another carbon filter.

TDI can be hazardous to humans and the wider

environment if it is not handled with care, even in very

small amounts.

To protect process operators, near neighbours

and the external environment, the foam process

is enclosed, extract ventilation is provided and the

exhaust stream is filtered with the Camfil Farr carbon

filter solution to remove all traces of TDI prior to

release to atmosphere.

Protecting production

More TDI-free dreams

Global demand is increasing for smaller, more power-

ful electronics and more advanced displays.

Micronic Mydata, a Swedish high-tech company

engaged in the development, manufacture and mar-

keting of production equipment to the electronics

industry, specializes in pattern generators and sur-

face mount technology.

A recent Micronic Mydata system delivery to a

major customer included Camfil Farr’s Gigapleat to

protect the production process for photomasking

equipment, an integral component in the lithographic

process of semiconductor manufacturing.

Gigapleat is a pleated carbon filter recognized

for its ability to effectively remove harmful gaseous

and airborne molecular contaminants in sensitive

manufacturing environments.

Camfil Farr’s vision is clear: clean air should be considered a human right.

The vehicle for the show is a large trailer truck

that is touring major European cities. During

stops, Camfil Farr air quality experts are track-

ing and comparing live air quality data and

providing information about the harmful effects

of air pollution, which directly affects air quality

indoors, where people spend about 90 percent

of their lives.

The trailer is 13 meters long and has almost

60 square metres of floor area divided into

a mini exhibition, an auditorium for up to 20

people, and four lab stations focusing on IAQ.

A public health concern

Air pollution and poor indoor air quality (IAQ)

become public health concerns and Camfil

Farr wants to inform the general public about

their impact on human health, well-being, per-

formance and productivity. At the same time,

knowledge about the importance of IAQ is

limited. Camfil Farr’s mobile exhibition is mainly

designed to inform politicians, the public and

the media about the importance of breathing

good quality air in the premises where we work

and live.

With test equipment, lab stations and film

presentations, this unique exhibition-on-wheels

clearly shows the type of pollutants contained in

“invisible” ambient air.

Reducing the energy consumption of build-

ing ventilation systems is another purpose of the

mobile exhibition. Electrical power consumed by

air handling units can be significantly decreased

by choosing the right filtration solution. In this

respect, IAQ – as defined by Camfil Farr – also

signifies clean quality air supplied in an energy-

efficient and sustainable way with our filters.

This rolling mobile lab and exhibition provide

a window on Camfil Farr’s world and our goal to

improve air quality, which has a direct effect on

quality of life.

Seeing theory in practice

In the mobile exhibition, visitors learn about IAQ

by watching a movie that explains the basics

about air pollution the sources of air pollution

and its health impacts.

This “theoretical presentation” is turned

practical at four lab stations (see next page),

where visitors learn more about particle quanti-

ties and sizes in outdoor air, how to select the

most energy-efficient filter, the filtration of gases

and the importance of consistent efficiency over

the lifetime of a filter.

Camfil Farr has almost 50 years of experi-

ence in the air filtration market. We have four

R&D centres around the world, dedicated to

learning even more about air quality and its

impacts. We believe that by sharing our know-

ledge, we can help increase well-being and

health at the same time as we help manage

energy consumption and increase productivity.

On the road for cleaner air and better filtration

Camfil Farr is now on a European road show. The objectives are to raise awareness

about the importance of Indoor Air Quality (IAQ), demonstrate the benefits of effec-

tive air filtration and explain how sustainable IAQ and lower energy consumption are

achieved with the right choice of filters.

Mobile lab stations put theory into practice

The four lab stations in the mobile exhibition illustrate some of the basic pillars of Camfil Farr’s clean air concept and air filtration technology.

What do you breathe?

Measuring and defining air quality is difficult

and complex. With the exception of oxygen,

nitrogen and carbon dioxide, the air contains

a number of contaminants that are harmful

to people. These are present in the air we

breathe. This lab station is equipped with highly

advanced measurement equipment to detect

different particle sizes. The smaller the parti-

cles, the easier it is to inhale them. The larger

the particles, the easier they are to capture in

a filter.

The station demonstrates why high-quality

air filters are required for good protection

against traffic pollutants, for example. It also

shows the air quality at the trailer truck’s cur-

rent parked location. The equipment measures

different particle sizes both before (outside)

and after (inside) the filter and then displays the

efficiency of the filter for visitors.

How can you save?

Providing clean air demands energy. But clean

air also saves lives and money. We need air

filters, but we also need to ensure that they are

sustainable and energy-efficient.

At this lab station Camfil Farr demonstrates

the difference that can be made by choosing

the right filter solution. With two identical air-

handling units operating side-by-side, showing

the air flow and energy consumption of two

similar filters, visitors can clearly see how much

energy can be saved.

This is especially important since 70 percent

of the electricity in a building’s energy profile

goes to heating, ventilation and air conditioning

systems.

How can you keep the city out?

Besides particles, gases have a negative impact

on health and productivity. Gases often have a

short-term effect on people, causing respiratory

problems and headaches.

Ozone and nitrogen dioxide are two impor-

tant gases to look at. This lab station shows the

current concentration of these gases (which will

depend heavily on the season) in the air around

the parked exhibition and a molecular filter’s

efficiency at removing these gases.

Environmental Medicine, Department of Public Health Services

What filters do you need?

It is virtually impossible to see all pollutants in

the air. Seeing the exact difference between the

qualities of two air filters is also very difficult.

This lab station uses smoke (an extremely

high concentration of particles) to visualize the

difference between two air filtration systems.

The smoke allows visitors to see the difference

between filtration efficiency and how a low-

quality product performs over time, compared

to a high-quality product.

Welcome!

Busy airports have high pollution levels and airport

officials are eager to prevent harmful gaseous pol-

lutants and odours from entering terminals through

ventilation and air conditioning systems.

CDG in Paris, the second largest airport in

Europe, is building its new S4 terminal to accom-

modate 7.8 million passengers in addition to the 58

million currently served each year.

CDG’s owner, Aéroports de Paris, is committed

to sustainability and reducing energy consumption.

All equipment and material for S4 must there-

fore comply with High Environmental Quality (HEQ)

standards.

Axima, responsible for engineering the climate

systems, has chosen to use only eco-responsible

suppliers. Camfil Farr, recognized for its track record

in sustainable filtration solutions, and for green prod-

ucts with low energy consumption, was first choice

for molecular filtration at S4.

This will be accomplished with several thou-

sand Camcarb Green cylinders to clean more than

700,000 cubic metres of air per hour for a healthier

and safer indoor environment.

Fresh, clean air is guaranteed for actors and audi-

ences at the Copenhagen Opera House/Royal Danish

Theatre, where all ventilation units are equipped with

our low-energy Hi-Flo XLT filters, and at the Vienna

Opera House (Wiener Staatsoper), where Hi-Flo

filters have been installed to ensure high-quality air

through fresh-air ventilation, which is preferred to air

conditioning.

HEQ for Paris-CDG

Live measurementsMorning air is different from afternoon air. City

air differs from country air. The mobile exhibition

has three air quality monitoring stations that

continuously report real-time air quality back to

the trailer from different world locations. These

measurement values are compared to local

conditions where the trailer is parked.

In the exhibition, visitors can also watch

a film about IAQ with commentary by Swedish

Professor Magnus Svartengren, a specialist in

occupational and environmental medicine.

“Air pollution is actually a mix of many

different substances. It consists of particles

containing compounds of chemical substances

which vary in size, such as very fine particles

from combustion processes. Pollution can also

consist of a number of gases, of which several

can act as irritants. Then there are chemicals

that can be outgassed from building materi-

als and other sources,” comments Professor

Svartengren in the film.

He continues: “These affect indoor air qual-

ity, which in turn can impact our performance

and health. Poor quality air in classrooms or

conference centres can cause headaches, for

example. Poor IAQ can also have local effects,

such as eye irritation, or affect the airways of

our lungs, aggravating people who have asthma

or causing us to cough. Air pollutants can also

affect lung development in children, or cause

cardiovascular disease in adults. Certain chemi-

cals can also cause lung cancer.”

The air filter market is expanding in Europe. It is

expected to grow even more when all new build-

ings have to meet “zero-energy” requirements

by 2020/21 (2018/2019 for public buildings).

A zero-energy (ZEB) building is a popular

term to describe buildings with zero net energy

consumption and zero carbon emissions annu-

ally. A ZEB is basically a residential or commer-

cial building with greatly reduced energy needs

through efficiency gains.

These “ZEBs” will need effective ventilation

supplying high indoor air quality (IAQ), which

in turn will require the use of high-quality air

filters.

Evolution of filter classes

Over the years, our industry has seen the basic

purpose of air filtration shift. Air filters used

to be selected to protect ventilation equip-

ment – today, their main function is to improve

the indoor climate and protect the health of

people. Today’s polluted air in urban environ-

ments may cause headaches, cardiovascular

and respiratory problems. Clean filtered air, on

the other hand, leads to improved work perform-

ance, reduced absenteeism due to illness and

enhanced well-being.

Over the years, filter classes have also pro-

gressed from low filter levels, such as G4 and

F5, to today’s high filtration classes, F7 and F9,

with F7 being the most common and minimum

class for guaranteeing acceptable IAQ.

Unfortunately, there is a paradoxical rela-

tionship between filter classes and energy sav-

ings because the better the filter, the higher the

energy consumption since a filter’s resistance

to air flow and pressure drop often increase.

Due to their resistance to the air flow, air filters

account for at least 30 percent of a ventilation

system’s energy consumption today.

With energy costs spiralling, the cost of

cleaning, supplying and exhausting air in build-

ings has consequently become a major concern

today and the choice of the right filters can

help. Improving the energy efficiency of HVAC

systems is another way to make buildings

greener and combat climate change. Camfil Farr

is well positioned to help customers reduce their

energy costs because our air filters have the

lowest pressure drop development. Simply put,

less energy is required to “push” air through our

filters, which also provide the added advantage

of maintaining their efficiency longer, compared

to low-cost products with poorly functioning

filter media and/or insufficient filtration area.

In Eurovent’s Product Group 4B “Air Filters”

(PG4B), we have discussed pressure drop

considerably and the energy classification of

filters. The Eurovent Guideline 4/11 – “Energy

efficiency classification of air filters for general

ventilation purposes” – is ready and published

on Eurovent’s website. Starting in January 2012,

Eurovent Certification will certify all fine filters

that will be assigned an energy efficiency class

(A to G) tested according to EN 779:2011. They

will also be classified according to their annual

EN 779:2011 – a step in the right direction

energy consumption, initial efficiency and mini-

mum efficiency (ME).

Let me now comment on EN 779:2011.

A welcomed initiative

The new European standard for air filters

(EN 779:2011) comes into force in autumn

2011. Its purpose is to classify air filters based

on their minimum filtration efficiency (ME) for

0.4 μm particles.

Camfil Farr welcomes the new standard

and considers it a step towards improving IAQ.

The industry has now voted for tougher require-

ments for air filters and the standard will be

published in August this year. National versions

will be available in mid-November, after which

the former standard will no longer apply.

In our view, the new standard will help

eradicate a number of problems related to

filter performance. One of these problems is

associated with electrostatic-charged synthetic

filters. These filters usually demonstrate good

initial filtration efficiency while they keep their

charge, but tend to discharge extremely rapidly,

often after just a few weeks of operation. F7

performance in the lab for an electrostatic-

charged filter can therefore decrease to F5

in real operating conditions, and sometimes

even more. Their cleaning ability deteriorates

considerably as a result. Unfortunately, far

too many European buildings are now using

electrostatically charged F7 filters that have

medium efficiency (ME) values between 5 and

10 percent. As a consequence, as much as 90

to 95 percent of the contaminants in outdoor

air find their way into buildings and pollute the

indoor environment.

By basing classification on an ME of at

least 35 percent for F7, the new EN 779:2011

standard will force these filters out of the

market. At the same time, it will contribute to the

development of synthetic filter materials offering

considerably higher particle separation.

Not all filters are the same – even in

the same class

Regrettably, the price for this will include higher

pressure drops and increased energy consump-

tion.

Camfil Farr has one concern about the new

classification: while the “worst” filters will vanish

from the market, there is a possibility that

“good” filters will be made “worse”. Although

energy savings can be achieved by having the

lowest possible pressure drop, such develop-

ment could be retrograde.

For example, for 0.4μm particles, our

Hi-Flo XLT7 (class F7) filter has an ME value of

56 percent. However, to be classified as an

F7 filter, the standard requires no more than

35 percent for a filter. Camfil Farr’s position on

this is clear: we will not lower the efficiency of

our Hi-Flo filters. Air quality would deteriorate

approximately 40 percent if we did.

However, there is a risk that other manufac-

turers will not think like us. They may see the

standard as an opportunity to reduce pressure

drop and, thereby, energy consumption. This will

unfortunately result in poorer air quality.

At Camfil Farr, we have always put every

effort into improving IAQ. Thus, no one is more

pleased than us that the new EN 779:2011 air

filter standard imposes tougher requirements

even if the requirements are not as tough as we

would have liked and do not meet the quality

standards set for our own air filters.

We welcome further debate and discussion

on this.

Camfil Farr’s City-Flo XL has been designed

specifically to deal with growing urban pollution

since it manages both particle and molecular

filtration in a single filter.

City-Flo XL cleans air to remove particles,

odours and gases – including ozone, carbon

dioxide, sulphur dioxide, carbon monoxide and

nitrogen dioxide – as well as volatile organic

compounds (VOCs) and polycyclic aromatic

hydrocarbons (PAHs).

Because City-Flo XL also contains activated

carbon, it removes odours that ordinary filters

miss. City-Flo XL is also extremely effective

against eliminating exhaust fumes.

Along streets and roads with heavy traffic,

City-Flo XL is ideal for use in office complexes,

shopping centres, schools and other public

buildings. The pressure drop across its unique

carbon-filled fibreglass media is very low, saving

energy and money for customers.

Eurovent certified

With City-Flo XL installed in the AHUs of public

and commercial buildings, occupants are guar-

anteed a high level of IAQ as set out in European

Standard EN 13779. The filter is also Eurovent-

certified and P-marked in Sweden. It has a low

initial pressure drop for energy savings, a new

conical bag design and an Ozone 3 rating.

Keep the city out with City-Flo XL

Easy installation

City-Flo XL uses the same single-piece plastic

frame found in many other Camfil Farr filters,

making installation easy if you are already using

our products. When customers have to upgrade

or add to existing filters, there is no need to

replace their old system. With the City-Flo com-

bination filter, they simply change out both the

bag filter and carbon filter.

Poor air is a growing problem in cities. Exhaust fumes, diesel particulates and ozone

generated by increased vehicle traffic contribute to air pollution. Sulphur dioxide, nitro-

gen oxide and other air contaminants are creating serious health problems. At the same

time, European requirements for better indoor air quality are becoming stricter.

Hotel guests are more demanding and discerning

today when they choose hotels. A green environmen-

tal profile is a selling point along with a reputation for

high comfort and cleanliness. Indoor Air Quality (IAQ)

falls in this category.

The five-star Berlin Marriot focuses sharply on

sustainability and Camfil Farr’s low-energy City-Flo XL

solution was chosen as the perfect filter to provide

guests with the best IAQ in accordance with the strict

performance requirements of EN 13779 for ventila-

tion in non-residential buildings.

City-Flo XL effectively removes particles and

odours to upgrade IAQ with the highest possible

energy savings, outperforming all other particulate

and molecular filters on the market.

Best IAQ at the Berlin Marriot

Largest contract to date in India

90,000 Hi-Flo XL filters to save 10 GWh in NorwayGK Konsern AS, the leading indoor climate contractor in Scandinavia, is installing

90,000 Camfil Farr Hi-Flo XL filters in the air handling units (AHUs) of its customers

in Norway to reduce their energy consumption. GK estimates that the filters will save

customers at least 10 GWh of electricity per year.

“10 GWh is actually a conservative estimate of the total projected annual savings when all the filters

are installed,” says Peder Midtstøl, purchasing manager for the GK Konsern AS, which has a share

of 20-30 percent of the professional construction market in Norway. Camfil Farr’s Hi-Flo XL is a new

generation of “green” low-energy filters that cuts the overall operating costs for ventilation systems

and improves indoor air quality (IAQ).

Battling urban pollution

For better IAQ in Norway’s urban areas, GK is also taking the next step in filtration by recommend-

ing customers to install Camfil Farr’s City-Flo XL for particulate and molecular filtration. This filter

is specially designed to battle urban pollution and has a proven broad spectrum capability against

concentrations of most indoor and outdoor pollutants (see separate article).

“As an example, I can mention that we’re now in the process of changing to City-Flo XL at a fire

station in central Bergen,” says Midtstøl. “IAQ has improved considerably since we started replacing

existing filters with City-Flo XL,” he ends.

Due to the phenomenon called temperature inversion, Bergen (photo above) suffers periodic

declines in air quality during cold winter spells and city officials are stepping up efforts to keep risk

groups from being exposed to outdoor air pollution (see AirMail No. 1, 2010). This has also led

to initiatives by facility owners and contractors to improve IAQ, which is directly impacted by air

pollutants entering buildings.

Over the past few years, Camfil Farr Power Systems

(CFPS) has focused on refining its project manage-

ment organization and building up a formidable pool

of international engineering expertise to serve the

global gas turbine business.

These efforts are paying off, as exemplified by a

Siemens order awarded to CFPS India and Germany

for one of the largest natural-gas-based combined

cycle power plants in the Indian private sector.

The plant, located near Rajahmundry and operated

by Konaseema Gas Power Ltd (KGPL), will add an

additional 820 MW of power with two new combined

cycle modules. Camfil Farr India is supplying intake

systems, diffusers, diverters and stack for two

Siemens SGT5-4000F turbines.

In addition to being Camfil Farr India’s largest

single contract to date, the KGPL project represents

a major breakthrough order where both the intake

and exhaust is being supplied for the same turbine

for the first time. CFPS was also a supplier for Phase

1 activities at the plant.

Taking R&D to new heightsIn late 2010, Camfil Farr opened a new

state-of-the-art Technology Center in Trosa,

Sweden. The new centre functions as a

2,500-square-metre innovation hub for prod-

uct and process solutions. It also features

the largest and most advanced laboratory for

Indoor Air Quality (IAQ) research in the air

filtration industry with gas chromatography

and scanning electron microscope.

Other facilities include a high-performance particle

filtration lab and comfort filtration lab with EN 779

(Europe) and ASHRAE (U.S.) testing capabilities; a

Power Systems and Air Pollution Control lab and

a molecular laboratory.

About half of the center’s space is used for Camfil

Farr’s own process development, including machine

construction, concept prototyping and optimization of

industrial processes for filter manufacturing.

The center includes a visitor’s center with full

lecture hall and direct access to all labs.
