Quadrafoam™ Air Filters

Quadrafoam™ and Quadrafoam II™ filters are ideal for telecom, medical, power gen, military/defense, and many other industrial and commercial products.  Quadrafoam™ and Quadrafoam II™ filters are configured in made-to-size aluminum-framed, cleanable filters, or cut-to-size pads, for fresh air intake and exhaust.  Quadrafoam™ and Quadrafoam II™ air filters are effective filters for GR-63-CORE and help enclosures meet GR-487-CORE and various MIL-STD, NEMA and IP ratings.  Quadrafoam II™ air filters are specially designed for harsh environments and are formulated to better withstand prolonged exposure to high temperature and high humidity environments.

Expanded on our specially designed Uni-Grid equipment, using .040″ thick, 3000 series aluminum. Uni-Grid expanded aluminum is approximately 85% open to maximize air flow. Quadrafoam™ and Quadrafoam II™ filters use Uni-Grid support on one or both sides.

Framed Filters +/- 0.06″  length & width, +/- 0.03″ thickness

Pad Filters +/- 1% (0.06″ min.) length & width, +/- 0.06″ thickness

Quadrafoam™ and Quadrafoam II™ are open cell polyurethane foams specially coated to provide improved flame, fungus, and UV radiation resistance. They feature deep loading, high dust holding capacity, low air flow resistance and mist elimination for use in extremely wide climatic conditions.

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

Quadrafoam II™ filter media is available in all frame models in various pore sizes (10 through 45 PPI Gray and Black).

Roll formed into a strong, sturdy one-piece channel, using 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.
