BOSA Microfiber Bag Filter

product image


Polypropylene Microfiber materials provide high efficiencies at low micron ratings. The layer configuration of the BOSA Bags includes proprietary Nanowave media and needlefelt outer cover. The multilayer configuration achieves a graded density structure increasing efficiency and adding life compared to a standard POMF Bag due to greater depth filtration. 


Precise particle retention allows use of BOSA bags in a wide variety of applications where absolute filtration is necessary. The Polypropylene composition allows for the BOSA Bags to absorb up to 15-20 times their weight in oil and last up to 18 times longer than traditional bags (depending on the application and particle distribution). 



• Absolute Micron Ratings (98%) from 3 to 100 Micron
• Microfiber Layers are Thermally-Bonded and contain no adhesive, Resin or Silicone
• Graded-layer configuration provides low initial pressure drop and maximum dirt holding capacity
• Wide chemical compatibility 


• Recommended changeout is 10-15 lbs. Differential Pressure
• Maximum Differential Pressure is 35 PSIG
