Uni-Foam fan air filters are designed to provide high dust arrestance where a permanent, cleanable filter is required in
medical equipment,
electronics,
computer,
telecom,
datacom and general purpose equipment. Uni-foam media can be used in a wide variety of indoor and outdoor applications. The media can withstand exposure to moisture, if installed in outdoor environments. The cellular media structure acts as a mist eliminator to reduce water ingress caused by rainfall or water splash. Certain Uni-Foam filter models are specifically designed for use in "limited-space" equipment.
Applications Each model performs with a high degree of dust arrestance when installed in medical, electronics and computer equipment where permanent type, cleanable filters are required. FF-2X, FF-3, FF-5, FF-5X filters have been specially designed for equipment where space is limited.

Media Uni-Foam media is a polyurethane foam, with an open cell structure, available in various pores per inch (PPI) ranging from 10 through 60 PPI. The random arrangement of strands and pores make this a filter media with tremendous dust-holding capacity and arrestance. This media characteristic also helps serve as a mist eliminator for applications where water droplets are in the air stream. The Uni-Foam media used on all dual-action filters has a flame resistant additive, making it self-extinguishing. The Uni-Foam media is bonded to the Uni-Grid support, thus making it inseparable after assembly.

Frame Roll formed into a strong sturdy one-piece channel, using .025" thick, 3000 series aluminum. Frame is tightly fitted to filter media and fastened with an aluminum rivet. The UL listing, model number and air flow direction are roll imprinted into the frame. Part number is metal stamped into frame for quick, accurate identification.
Uni-Grid Support Expanded on our specially designed Uni-Grid equipment, using .040" thick, 3000 series aluminum. Uni-Grid expanded aluminum is approximately 85% open to lower resistance. Uni-Foam filters use Uni-Grid support on one side.
