Oil Absorption Liquid Bag

The high density of small diameter fibers compared to that of a standard needle felt enhances particle retention, leading to superior, highly effective and efficient filtration. The fully welded, multi-layered construction provides an exceptional depth of filter media and long service life. The bags are used for those critical applications when highly efficient operation and effective particle holding capacity is required.

All seams are fully welded, producing strong, reliable joints with no by-pass or loose sewing thread. Seams are both strong and flexible, allowing the filter bag to form to the restrainer basket. The seam edges are heat sealed, eliminating possible loose fibers. This results in a filter bag with durable performance for the most demanding applications.

Material: polypropylene (PP) microfibers

Micron Ratings: 1-100μ

 High oil and hydrocarbon absorption capacity

 Substantially reduces oil and grease from aqueous based liquids

 Unique three layer construction results in maximum exposure time at minimum flow rate

The top disc pre-filter material removes particles prior to the absorption of hydrocarbons

Particle removal efficiencies of up to 99%

 3 or 4 layers depending on micron rating 

 Large surface area

Has higher capacity than most other bags on the market

Designed to minimize contamination during changeover


Materials: oil adsorption polypropylene microfibers

Micron Ratings:  1-100micron
