Product description
Oil absorbing filter bag for liquid filtration and oil removal
The Oil Absorption Filter Bag is designed for liquid filtration applications where free and emulsified oils must be removed from process fluids. The filter bag combines oil adsorption with optional particle filtration, allowing simultaneous removal of oil contamination and solid particles.
This filter bag is commonly used in industrial processes where oil carryover negatively affects product quality, downstream equipment or discharge water quality.
Filtration and adsorption principle
The Oil Absorption Filter Bag is manufactured from multiple layers of ultra fine polypropylene microfiber media. The structure provides a very large active surface area, allowing oil molecules to be adsorbed within the filter media while liquid passes through.
Depending on the selected variant, the filter bag can also provide particle retention as part of the filtration process.
This combined mechanism provides:
-
efficient oil adsorption
-
optional particle filtration
-
stable pressure behaviour
-
extended service life
Design and construction
The filter bag is manufactured from virgin polypropylene microfiber using melt blown production technology. The multi layer depth structure supports both adsorption and filtration without the use of chemical binders or additives.
Key construction features include:
-
high oil adsorption capacity
-
multiple layer depth media composite
-
welded or stitched seam options
-
sealing collar options in plastic or metal
-
stable and flexible bag structure to ensure correct alignment in the housing
The design minimises bypass and supports consistent filtration performance.
Performance characteristics
The Oil Absorption Filter Bag offers:
-
high oil retention capacity
-
optional particle retention down to fine micron levels
-
low pressure drop during operation
-
predictable change out behaviour
Recommended filter change out is typically defined by pressure differential or oil saturation level.
Available variants
The Oil Absorption Filter Bag is available in multiple configurations to match process requirements.
