The oil absorbing filter bags, or oil degreasing filter socks, oil removal bags are specially designed for an application which demands to remove oil and other impurities from water or wastewater in industrial filtration. The oil absorbent filter bags have a unique conformation of multiple layers of oil absorbing (oleophilic) materials combined lining protection mesh, and nonwoven filter fabrics outside, which has excellent oil absorption capability, up to 95% filtration efficiency and good durability. Furthermore, the 100% PP material make it acid and alkaline-proof, safe for foodstuff contact, the hot melt joint also increases stretch resistant and no chemical release.

Bonfilt’s oil absorbing filter bags has a large oil absorbing surface area and excellent oil absorption capability could retain 20 times its own weight oil. Five different size and different micron rating 1 to 50 micron available, fit into any standard size 1# or 2# filter housing.

The oil removal efficiency of these oil absorbent filter bags is dependent on the type of oil you intend to remove as well as the differential pressure across the bag filter media. The greater the differential pressure the greater the propensity will be for the oil droplet to deform and migrate downstream which you don’t want.

For this reason, we suggest you to use pressure gauges on your filter housing to decrease your risk of forcing oil droplets downstream.
