PolyFold™ Filter Bag

Summary

Product identification

The PolyFold™ Filter Bag is a proprietary filter bag constructed of dual-sided extended life felt.

Features

• The dual-sided, extended life felt construction provides maximum dirt holding and a high flow rate.
• 240% more surface area than a standard bag.
• Fits in a standard basket, so no retrofit is required.
• 4X+ dirt holding capacity* results in longer life and fewer change outs.
  • *Compared to a standard felt bag. Based on lab testing using water and test dust.
• Polypropylene center tube supports filtration media, aids in insertion of filter bag, and accepts a bag magnet.
• PolyLoc® ring eliminates liquid bypass.
• Mesh cover assists in insertion and removal of filter bag.
