Air filters save energy and destroy bacteria and mould A range of air filter cartridges

called Bacti-cell are now available

from the Nationwide Filter ‘Co

(NFC) Ltd of London, UK. The

company claims that independent

trials have shown that in use the

filters provide energy savings of up

to 30%, and a 50% reduction in

viable cell count, compared with

conventional bag filters.

They have a large material area

which provides lower initial

resistance. According to

Nationwide, a typical F8 bag filter

can cause a pressure drop of 150 Pa

when it is first installed, while a

comparable F8 Bacti-cell filter will

cause a,hrop of 85 Pa. The increased

material area also takes longer to

clog. Bactiguard, an anti-microbial

agent which is used in the filters,

eradicates bacteria, moulds and

yeasts when they come into contact

with it.

Four different grades of Bacti-

cell classified as F6 to F9 are

available, and there are three

standard sizes which handle air

volumes up to 1.39ms/s. The

cartridges can be mounted

vertically or horizontally.

Membrane cartridges tackle aggressive chemicals Tetpor Plus is the latest addition to

the range of cartridge filters that is

offered by UK-based Domnick

Hunter Ltd. Designed to filter

aggressrve chemicals, such as acids,

alkalis and organic solvents, these

membrane cartridges tackle

contaminants that exist at the sub-

micron level.

They are constructed from a

fluropolymer, and comprise an

absolute rated polytetra-

fluoroethylene (PTFE) membrane

which is supported by PFA

hardware and PTFE-encapsulated

O-ring seals.

Available in four ratings,

ranging between 1 yrn and

0.05 pm, Tetpor Plus provides

optimum flow rates, they are

resistant to high temperatures and

offer excellent chemical

compatibility, says the company.
