Ultra-Web SB Pleated Bag Filter

Pleated filter bags built with Ultra-Web® SB media deliver longer filter life, higher efficiency and offer greater energy savings than traditional filter bags.

The bags feature a spunbond substrate covered in a web of fine fibers 0.2 – 0.3 microns in diameter that trap dust at the surface of the filter. This advanced surface loading prevents particulates from settling in deep in the filter substrate, allowing Ultra-Web SB filter bags to last up to twice as long as traditional bags. The pleated construction increases the surface area of the filter giving you more filtration power with each bag.


  • Spunbond substrate stands up to high temperatures, chemicals, moisture and abrasive dust
  • The Electrospinnng process produces exceptionally strong fibres as small as 0.2 – 0.3 microns in diameter
  • Fine fibre web traps dust on the surface of the filter
  • Pleated bags offer twice the filter area to increase efficiency and decrease pressure drop
  • 2-3 times the filter life over traditional polyester felt bags
  • Shorter bag height allows for a larger dropout area and less opportunity for bag abrasion
