Reverse Air Filter Bags

 

Reverse Air Dust Collector Bags

Reverse Air bags are cleaned by low-pressure backflow and gentle collapse/expansion cycles. We manufacture to your exact housing, cleaning method, and process conditions for long life and consistent low ΔP.

  • Media: Polypropylene, Polyester, Acrylic, PPS (Ryton), Aramid (Nomex), P84, PTFE, Fiberglass
  • Top options: Plain Top, Snap Band, Flanged, Hemmed, Compression Band, Spreader Rings, Hanging Loop
  • Bottom options: Disc/Plain, Wear Cuff/Tuff Cuff/Super Tuff Cuff
  • Reinforcements: wear cuffs and patches, anti-collapse rings, ground wires/tabs
  • Finishes: ePTFE membrane, antistatic, FR, singed, glazed, chemical-resistant
  • Fast lead times & plant-specific stocking programs

How to Measure

  1. Flat Width (FW): measure the bag opening laid flat (in or mm)
  2. Overall Length (OAL): top to bottom (in or mm)
  3. Tube Sheet (Cell Plate) Hole Diameter and Thickness (in or mm)
  4. Top/Bottom Options: choose from tables below (add photos if non-standard)
  5. Operating Conditions: temperature, moisture, chemicals, abrasion
