Quadrafoam™ Air Filters


Protect equipment with fire resistant, cleanable filters

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 industrialmedicaltelecom, and military electronics air filter applications. Quadrafoam™ air filters are the ultimate solution in networking and communications equipment where compliance to NEBS, ATCA and other industrial computer specifications are required.


More Information

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.
