Design engineers may not know they need a non-conductive air filter in their cooling system until it's too late. That's where Universal Air Filter (www.uaf.com) can help. Non-conductive filters are needed when space is limited and the filter frame may contact electrically charged surfaces or backplanes. This can occur in a variety of applications such as ATCA and MicroTCA chassis, 19" rack mount units and 1U high enclosures. Universal's non-conductive Flex-Frame filters feature flame retardant, polypropylene plastic designed to meet stringent filtration and flammability requirements of Telcordia NEBS, CE and UL.

In addition, the non-conductive, flexing design fits ever-shrinking equipment footprints and is ideal in applications that demand that filters "snake" around components, conform to a radius-type bezel or a curved track.

Flex-Frame filters are available with Quadrafoam filter media in various pore sizes (20 through 45 PPI green), and (10 through 60 PPI gray or black). A solvent-resistant, two-part bonding material unites frame and filter media making them inseparable.

Universal Air Filter products meet the following standards and classifications: UL 94HF-1; UL 900 Class 2, CE; Telcordia NEBS GR-78-CORE and GR-63-CORE; and, RoHS Compliance. When used as part of a fire enclosure, they also may be configured to comply with flame-drip requirements described in UL 60950 and EN 60950.

A free, round-the-clock air filter prototype service is available to design engineers worldwide at www.uaf.com. The Internet-submitted prototype request form, or a quick phone call, fax or e-mail, is generally all it takes to get the necessary information so the custom prototype can be produced and shipped within five working days.
