Retrofit Filter Cartridges
to fit Competitive Dust Collectors

  • Improve the performance or solve problems of existing collector systems. Farr filter cartridges are made with PolyTech media, the most advanced pulse-cleaned media ever made.
  • The HemiPleat separator bead opens up the pleat uniformly, allowing more effective cleaning and lower pressure drop.
  • Farr offers replacement upgrade cartridges to fit these and more:
American Air Filter® Torit®
MAC Equipment® UAS/Dust-Hog®
Pneumafil® Wheelabrator®

Performance Guarantee (PDF)View our Performance Guarantee (PDF) - HemiPleat will run at a lower pressure drop (to save energy), meet or exceed current collection efficiencies, and last longer - or your money back!

Poly Blend Filter Media

  • HMPTS - PolyTech™ Standard (color: green) - MERV 10/11 Proprietary blend of cellulosic fibers and polyester fibers with a moisture resistant silicone treatment for optimum dust release characteristics yielding long service life at high filtration efficiencies.
  • HMPTC - PolyTech™ Conductive (color: black) – MERV 10/11 Base HMPTS media described above, chemically treated and impregnated with carbon for static dissipation.
  • HMPTF - PolyTech™ Flame Retardant (color: off white with yellow stripes) - MERV 10/11 Base HMPTS media described above, chemically treated with a fire retardant.
  • HMPTU - PolyTech™ Ultra High Efficiency (color: white/green) - MERV 15/16 Base HMPTS media with a microfiber synthetic melt blown surface laminate that yields the industry’s highest filtration effiency possible at 99.999% on 0.5 micron and larger particles by weight.
  • HMPTUF - PolyTech™ Flame Retardant Ultra High Efficiency (color: white/off white media) - MERV 15/16 Base HMPTF fire retardant media described above with a microfiber synthetic melt blown surface laminate that yields the industry’s highest filtration effiency possible at 99.999% on 0.5 micron and larger particles by weight.
  • HMPTNFR - HemiPleat Nano FR (Color: white) - MERV 14/15 Base HMPTF flame retardant media with a microporous nanofiber coating. The nanofiber coating is applied to the upstream side of the filter for higher filtration efficiencies and improved dust release which makes this new material far superior to any other commercial filter media available.
  • HMPTNST - HemiPleat Nano (Color: white/green) - MERV 14/15 Base HMPTS moisture resistant silicone treated media with a microporous nanofiber coating. The nanofiber coating is applied to the upstream side of the filter for higher filtration efficiencies and improved dust release which makes this new material far superior to any other commercial filter media available.
