BOSA Absolute High Efficiency

BOSA Absolute High EfficiencyMicrofiber Filter Bags

  • Absolute (98%) micron ratings from 3 - 25 micron
  • Microfiber layers are thermally bonded and contain no adhesives, resin or silicone
  • Graded-layer configuration provides low initial pressure drop and maximum dirt holding capacity
  • Wide chemical compatibility
  • Excellent replacement bag for discontinued FSI styles

High Efficiency Microfiber Materials

Polypropylene microfiber materials provide high efficiencies at low micron ratings. The layer configuration of the BOSA bags includes proprietary nanowave media and a needlefelt outer cover. The multilayer configuration achieves a graded density structure increasing efficiency and providing longer life than standard POMF bags, due to BOSA's 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.) Recommended changeout is 10-15 lbs. differential pressure. Max differential pressure is 35PSIG.

Fully Welded Liquid Bags for Unmatched Reliability

AJR Filtration is committed to providing filtration solutions to improve performance. Our fully welded liquid bag filters provide superior results for the same cost as sewn felt bags. Fully fused seams ensure no chance of bypass through stitch holes, giving you cleaner filtrate, and the construction provides higher burst resistance due to the exceptionally strong fused seam. 

AJR backs this up with great in-stock availability of common sizes and fast lead times for made to order styles. Choose from polyester or polypropylene media with P, F, OSS, or RP flanges.
