Twenty Years of Experience Supplying Advanced Bed Protection Filter Products to Enhance Operations


We design all of our AFS filter products with uniquely-shaped, high alumina, inert filtration grading disks. This feature helps address multiple industrial problems with a single vessel and mitigates pressure drops caused by the accumulation of fouling agents at top grading layers of your hydrotreating reactors or other fixed bed units. Our bed protection filter products come in a wide range of sizes including:


  • 10 mesh size to filter large iron scale and polymerization particles
  • 25 mesh size to filter carbon and other medium-sized fines
  • 50 mesh size to filter iron sulfide, coker and solid silica fines
  • 60 mesh size to filter ultra-small, sub-5 micron fines
