Uni-Foam Air Filters

High dust arrestance, low pressure drop washable media

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 foam 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 air filter models are specifically designed for use in “limited-space” equipment.

 

Applications

Each uni-foam air filter 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. Order a free air filter prototype for your application today.

Unifoam filter media is available in all frame models in various pore sizes (25 through 45 PPI Green and 10 through 80 PPI Black).

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.

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.

Roll formed into a strong sturdy one-piece channel, using 0.025″ thick (0.032” thick for FF-2X), 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.

In addition to the standard roll formed frame design, more custom options are also available.  The Windowpane filter design allows for a customized, aluminum ”frame-n-pane” design that integrates the frame and a series of crossing, reinforcing intermediates that provide media support.  The Flex-Frame filter allows for a customized, flexible polypropylene ”frame-n-pane” design that integrates the frame and a series of crossing, reinforcing intermediates that provide media support.
