Hemipleat Retrofit Cartridges Offer Upgraded Dust Collector Performance


Jonesboro, Ark., February 2007- A full line of "HemiPleat(TM)" retrofit
cartridges from Farr Air Pollution Control (APC) may be used to upgrade
performance or solve problems of existing dust collector systems. The key to
enhanced performance is a patent-pending pleating technology that opens up
the pleats uniformly for more effective cleaning and better airflow. This
filtration upgrade can greatly extend service life and reduce pressure drop
compared to competitive dust collector cartridge filters. HemiPleat retrofit
filters are available to fit virtually all leading brands of dust collectors
that use cylindrical cartridges.

The Farr retrofit cartridges are made with the industry's most advanced
pulse-cleaned media, the HemiPleat "PolyTech(TM)" media. This silicone-treated
polyester/cellulose blend offers high moisture resistance and excellent
filtration efficiency - 99.99 percent on 0.5 micron particles and larger
(MERV 11/12). For demanding applications, Farr APC also offers an ultra-high
efficiency PolyTech media (99.999 percent or MERV 15/16 efficiency).
Flame-retardant cartridges are available for increased fire risk
applications, as well as carbon impregnated cartridges for static
dissipation.
