The Global Catalog is a quick reference to our filter media for Transportation Filtration. Developed together with sales, marketing and product development, it is aimed to help communication on our product families.

4 product families: Air, Oil, Fuel and Cabin Air are explained in detail including positioning and performance.

We will also explain and show visually the difference in our Series – did you know we have 400 series Oil products with Highest levels dirt holding capacity, Highest levels hot oil resistance and service life and which requires no wire back or support layer. You can learn more about this product here. (See page 8 or more details)

To make it easier – we will show you at Filtration 2014 how we have made this catalog an App! Come and see us on stand #402 in Baltimore to learn more.

If you are not able to join us in Baltimore, please contact your sales person for more information.

Natural Gas can be used in place of gasoline or diesel in vehicles. Advantages of natural gas include:

— Combustion produces fewer undesirable gases than gasoline or diesel.

— More energy per molecule of CO2 produced.

— Does not contain any lead, thus eliminating sparkplug fouling.

— Lower fuel losses, due to closed systems.

— It is safer than other fuels since it is lighter than air and in the event of a spill disperses quickly when released.

— Lower maintenance costs.

Natural gas may be used in traditional internal combustion engines that have been modified or in OEM engines designed to run natural gas. Natural gas may be used alone or in combination with gasoline (duel fuel) or with diesel (bi-fuel).

Natural Gas is stored on the vehicle as a liquid (LNG-Liquid Natural Gas) or as a gas Compressed Natural Gas (CNG). In most cases, how the fuel is stored is not a factor. What is important is that the fuel must be supplied to the engine in gaseous form at specified purity pressure and temperature.

Water, dust, sand, dirt, oils and other contaminants in the fuel can be detrimental to the operation of natural gas engines. The challenge is to develop fuel filters that capture traces of water, oil or other contaminants protecting the engine against damage. In most cases a filter is included which filters the fuel as part of the fuel delivery system. Ahlstrom is actively assessing the technologies used with a view to designing substrates.

The challenge of designing the filter is complicated by the choice of storage and the associated pressures, temperature and flows:

— A typical CNG fuel system is comprised of tank storage, a fuel fill system, fuel lines, regulators and a high pressure fill system. CNG is stored at pressures up to 3,600 psi. Fuel lines are connected to a pressure regulator that reduces engine pressure, where a second regulator controls the engine fuel requirements. CNG is infused with an odor agent so that leaks can be identified by smell.

— The LNG fuel system is a low pressure system designed for normal operating pressure of 230 psi. When LNG needs to be converted for use, it’s drawn from the tank, run through a vaporizer to convert to gas and supplied to the engine at the required pressure.

Dear Customers,

Our Product Development teams continue to be hard at work doing what we do best, exploring new fiber, chemistry and process technologies we can marry together to bring you new and innovative products. Cellulose is still the predominant fiber in many of our best performing products and though it has been used for many years we continue to explore and find unique ways to utilize this versatile fiber. Synthetic fiber usage is growing and whether we optimize these fibers on our wet forming assets or explore polymer forming technologies to bring new synthetic webs, our teams are determined to develop new solutions. Chemistry will always require heavy focus from our teams as we look to improve filter integrity, optimize processing on pleating lines, offer energy savings and make the products safer to handle.

One example where the merger of these technologies is paying off is the 100% synthetic media we are bringing to market for oil applications. Granted, 100% synthetic in itself is not unique, but we believe this wet formed synthetic web coupled with our saturation and chemistry technologies will bring a unique and valued product into the market. A key goal is to avoid the wire mesh and slow co-pleating required in current approaches.

Many indicators point toward the need for more highly engineered products and thus our teams are exploring improved composite materials. So another example is media with unique and engineered pore structures coupled with the right compositing and lamination technologies needed to meet the ever growing demands you face in Transportation Filtration applications.

Of course all these innovations and developments do not happen on their own. We have a diverse and experienced group of Product Development professionals. This is a passionate group that takes great pride in the work we accomplish. We work hard to meet the regional challenges we face but mostly we are a global team collaborating and sharing our know-how and expertise to meet the demands of you, our customers. I would like to take this opportunity to introduce you to the PD Managers that lead these efforts. Whether it is at your facility, an Ahlstrom site or an industry event, please take the opportunity to discuss your current and future challenges with us.

Fully Synthetic Oil Filter MediaClean engine oil keeps the engine performance consistent and protects the engine from impurities. Performance requirements for Oil filters are increasing along with higher performance demands and more challenging environments. Some examples are: higher engine temperatures, more challenging environments with turbo, direct injection, start/stop technologies.

These trends will continue to raise the performance requirements for filter media as well as the need toward more synthetic and high performance filter media.

We have been developing new filter media to fulfill these needs. We are now developing a fully synthetic filter media which is able to hold its structure in hot temperatures without any support layer. This new product will be able to offer significant cost savings in terms of materials used and in the processing time.

New products We will showcase these new products during the Filtration show in Baltimore – come and see us at our Stand # 402.

FLAIR (flame retardant, water durable)Why flame-retardant filter media in air intake filters?

– In air intake filter applications a fire risk or even the chance of an explosion has a high likelihood of occurrence

– If media is not flame-retardant, embers burn the media or even ignite the filter, resulting in expensive engine damages or possibly even worse scenarios

– Flame-retardant air media minimizes the risk of a possible fire source from air intake

Why flame-retardant water-durable filter media in air intake filters?

– Majority of the flame-retardant solutions are “washable”, meaning that if an air filter is treated with water (high humidity environment), it loses its flame retardant properties

– Flame-retardant water-durable air media minimize the risk of a possible fire source from air intake even in environments with high humidity or after a “filter washing” process

Why Ahlstrom Flair?

– Ahlstrom Flair is a portfolio of flame-retardant water-durable air filter media

– Flair portfolio is globally available

– Flair portfolio complies with international standards

– Flair portfolio complies with the most severe car industry requirements

– Flair portfolio is an “eco-friendly”, bromine-free solution
