Quadrafoam™ Air Filters

Quadrafoam™ and Quadrafoam II™ filters are configured in made-to-size aluminum-framed, permanent type cleanable filters for fresh air intake and exhaust, or by themselves in cut-to-size pads.  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. Therefore, Quadrafoam II air filters are an effective filter for mist elimination, and assist enclosures in meeting various MIL-STD, NEMA and IP ratings.

Quadrafoam II™ air filters support customer outside plant enclosure compliance in the areas of flame, fungus, and corrosion resistance. Customer products configured with Quadrafoam II™ air filters have been environmentally tested to withstand dust intrusion and wind driven rain as detailed in NEBS GR-487-CORE.

We suggest you test all Quadrafoam™ products to determine how they can contribute to your product.

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).

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 and low air flow resistance for use in extremely wide climatic conditions.

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.

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.
