Microfiber filter bag specifications and ordering information
Why Choose High-Efficiency Microfiber Bags
- Micron ratings from 0.5A to 90A (absolute-rated family)
- Industry standard and custom sizes available
- Choice of steel ring or plastic flange styles
- Wide chemical compatibility
- Excellent oil-absorbing capability (application dependent)
- Handles available on ring-style bags
- Typical efficiencies to 95% at rating
High-Efficiency Bag Materials
Microfiber media provide high efficiencies at low micron ratings. An optional needle-punched felt prefilter layer can be added to create a graded-density profile, increasing surface area and extending service life. The multilayer construction balances fine capture with low pressure drop.
Bag Styles
Ring-style bags are supplied with a galvanized steel ring (stainless steel optional) sewn into the top of the bag and include a handle. Plastic collar (flange) styles use a specially designed flange sewn to the top of the bag for positive sealing in compatible housings.
