In addition to the standard PolyTech™ filter media, HemiPleat® is also avaliable with Nano fiber media. Nano technology allows base material to have larger pore sizes, thus reducing the pressure drop and allowing the nano fibers to provide a superior efficiency layer.

HemiPleat Nano media improves filtration efficiencies, is more durable, and can withstand rigorous pulse-cleaning. These advantages extend filter life and lower operation costs, saving you money.

Key Benefits of HemiPleat Nano

  • MERV 14 efficiency rating - higher than base paper rating of MERV 10 and competitors’ MERV 13 Nano Web product.
  • Delivers long-term low pressure drop on difficult applications like laser and plasma cutting, welding, thermal spray, etc.
  • HemiPleat Nano coating is thick, durable and can be seen. Competitive Nano coatings are so thin they can’t even be seen - is it even there?

What is the efficiency rating?

The photos to the right show Nano fine fiber layer (image A) applied to the surface of base cellulose fibers (B) to increase efficiency from a MERV 10 up to a MERV 14, which is higher than most other nano fiber filters on the market at MERV 13.

MERV is an ASHRAE standard efficiency scale going from 1 to 16, 16 being the highest. Camfil Farr APC also offers our High Efficiency (HE) media which has a MERV 16 rating for maximum initial efficiency. Tested efficiencies of 99.999% on 0.5 micron and larger particles by weight have been proven. Mass emissions are below 0.001 gr/dscf on most applications.

Why is HemiPleat Nano better?

  • Lower pressure drop through open pleat spacing improves cleaning efficiency, which will reduce energy costs through less compressed air consumption during cleaning in many applications.
  • More media is available for filtration, resulting in improved performance and longer life.
  • The separation beads, not the media pleats, contact the inner cage, protecting the media from frictional damage.
  • Camfil Farr APC guarantees performance in writing—ask about the HemiPleat Guarantee.
