BHA Preveil ePTFE Membrane & Filters

Membrane Bag Filters

BHA® Preveil® membrane is an expanded microporous PTFE membrane (ePTFE) that is bonded to the surface of conventional filter media, including felts and woven fabrics.

Made from virgin PTFE resin, BHA Preveil membrane is manufactured in our own climate-controlled cleanroom environment, which allows us to create a membrane with exceptional lamination strength and controlled specifications. BHA Preveil membrane filter media is tested and inspected to assure the filter bags are the highest quality.

BHA Preveil membrane is ideal for high moisture applications and operations requiring extremely high collection efficiency or increased air volumes. It is designed to be used with virtually every style of filter bag, and can be used in pulse-jet, plenum pulse, reverse air, shaker and cartridge dust collectors.

BHA Preveil Advantages

  • Highest filtration efficiencies (99.99+%) for lowest possible emissions
  • Excellent dust cake release on cleaning helps keep pressure drop low and maintain stable system operation
  • Reduced agglomeration for hassle-free baghouse operation
  • Greater airflow and/or lower energy consumption helps provide quick return on investment
  • Sub-micron filtration
