Pleated Filters

Pleated dust filter bags are made of polyester spun bond material. The pleats greatly increase the filter surface area allowing for lower air to cloth ratios in the same space.

Available in thin and long lengths or short and fat with lengths to 96”. Pleated filter bags are normally manufactured in the same diameter as the bag that they replace.

  • Working continuous temperature: < 248 °F
  • Peak temperature: 302 °F
