SAUGET, Ill. — Quadrafoam air filters from Universal Air Filter® help power-gen, HVAC and general industrial applications meet the strict UL 508A safety requirements intended for industrial controls 600V or less, in preventing arc flash and shock hazards within the prohibited approach boundary. UAF’s UL 94 HF-1 rated, non-conductive Quadrafoam filters provide a protective barrier between the internal controls and the panel exterior.
The UL 508A requirement specifies a minimum distance between arcing components and the ventilated panel exterior, which depends upon the short circuit current rating and appropriate classification. In order to save space, a panel may be produced to a smaller dimension. Although a thinner, shallower panel may encroach on the specified safe distance, it helps if the ventilation openings are covered internally by a protective barrier. UAF’s non-conductive Quadrafoam filters can be installed along the interior face of the ventilation openings in the panel to serve as the protective barrier.
A design engineer looking to evaluate a Quadrafoam filter or any other UAF product can access UAF’s complimentary, round-the-clock prototype service available worldwide via www.uaf.com. The prototype service provides design engineers with assistance in meeting critical design, testing and evaluation deadlines for air filter media.
