Bag Filters
United Filters International manufactures heavy duty filters for industrial applications.
UFI Liquid Filter Bags are a cost effective alternative for most fluid applications. Manufactured using several media options to insure fluid compatibility these bags are available in 1 absolute to 1500 nominal micron ratings and are 100% interchangeable with all industry standard #1 through 9 filter bag housings.
Used extensively in hydrocarbon and natural gas processes as well as RO pre-filters, liquid filter bags offer ease of removal while containing contaminants for proper disposal.

UFI Liquid Filter Bags

Media:
- Polyester or polypropylene felts, nominally rated at 50% efficiency. Its cost effectiveness makes it ideal for applications up to 200° F.
- Polyester multifilament meshes, nominally rated at 90% efficiency.
- Polypropylene Mesh Similar to nylon mono filament mesh, which has better acid resistance than nylon and is more cost effective for temperatures up to 200° F.
- Nylon mono filament meshes, nominally rated at 90% efficiency.
- Polypropylene high efficiently micro fiber, nominally rated at 95% efficiency.
- Polypropylene oil removal, nominally rated at 95% efficiency.
- Polyester or Polypropylene Graded Density, 99% absolute efficiency.
- Teflon, nominally rated at 95% efficiency.
- Cotton, nominally rated at 90% efficiency.
- Oil absorbing bags and inserts (hold 25 times their own weight in oil/petrochemical.
