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

UFI’s Melt Blown Cartridges is manufactured from 100% Polypropylene construction offering excellent filtration and good thermal stability. The unique density gradient construction maximizes efficiency and minimizes pressure drop. This filter will not impart taste, odor, or color to the filtered product and has superior chemical resistance for process fluid applications. Grooving option effectively doubles the surface area providing lower clean pressure drop, increased dirt holding capacity and longer life. All these qualities resulting in a lower cost of ownership.

Cartridges are available in one to 50-micron ratings, 2.5-inch and 4.5-inch outside widths and 4-inch to 50-inch lengths, and various end cap configurations (see below) for a broad array of applications.

Lifting Devices:

  • Galvanized carbon steel
  • Stainless Steel
  • Molded plastic
  • Woven fabric

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.
  • Poultry and meat washing & packing

Applications:

  • Pre RO membrane protection
  • Sand & algae, removal from sea water
  • Filtering amine, oil, gas, glycol, naphtha, waist vegetable oil and bio-diesel
  • Gas purification processes
  • Offshore filler stations
  • Food, beverage, potable water
  • Dairy processing
  • Pulp removal
  • Poultry and meat washing & packing
