Quadrafoam air filters offer low pressure drop, fire resistance, and the ability to capture large amounts of airborne dust in industrial enclosure applications. Quadrafoam is ideal for use in equipment where permanent, cleanable filters are most appropriate.
Applications
Quadrafoam air filters are offered in a broad range of porosities (PPI) to meet custom filtration performance requirements. They also comply with UL 94 HF-1 self-extinguishing flame safety standards for electronics in
industrial,
medical,
telecom, and
military electronics air filter applications. Quadrafoam air filters are the ultimate in
networking and
communications equipment where compliance to NEBS, ATCA and other industrial computer specifications are required.
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.
Both Quadrafoam and Quadrafoam II 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. We suggest you test all Quadrafoam products to determine how they can contribute to your product. Order a

Frame
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.
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 maximize air flow. Quadrafoam and Quadrafoam II filters use Uni-Grid support on one or both sides.
