DuoLine OilOut Bags

Designed to provide effective oil absorbing capacity in a wide range of applications using a variety of polypropylene media, there are 2 products in this range: DuoLine HO and DuoLine PA bags.

DuoLine HO

Designed to give high levels of efficiency and oil retention. The multi-layered combinations of needlefelt and micro-fibre media are supported in a heavyweight scrim. This bag offers long service life and significant dirt holding capacity.

  • Polypropylene, rated 1- 25µm
  • High efficiency filtration rating
  • Double integral handles

DuoLine PA

Designed for maximum oil retention. The needlefelt bag contains over 1Kg of polypropylene microfibre media. This bag has a unique flow path which directs the fluid down the body of the bag for maximum contact time resulting in a highly efficient oil retaining device.  Polypropylene microfibre, rated 50µm.

  • Up to 25 x times its own weight in oil capacity
  • Double integral handles

Available in 2 diameters – 4¼” and 7”, all fitted as standard with a top ring locator in various materials and styles. All DuoLine OilOut bags are designed to filter from the inside to out leaving the contamination inside the bag for simple disposal. These needlefelt bags can be used for both pre and final filtration duties.
