Air Filters Are Flame Retardant

A new UL-recognized Quadrafoam air filter medium has been designed specifically for use with forced air cooling systems in electronics enclosures. Quadrafoam open-cell polyurethane foam media are treated with a thinner layer of flame-retardant coating, making them useful in applications exposed to harsh environments, high-temperature and high-humidity conditions. The coated foam contains an anti-microbial additive with a fungus growth rating of zero. The filter comes in a wide range of pore sizes, giving the user a combination of dust capturing capability and low resistance to airflow. And it meets UL 94 HF-1 flammability requirements and complies with European Standard EN 60950 specs. When used as part of enclosures that must be protected against fire, the filter may be configured to meet the flame-drip requirements described in UL 1950 and the EN 60950.
