Universal's Flex-Frame air filters use flexible, flame retardant, polypropylene plastic frames. The product line meets the stringent filtration and flammability requirements of Telcordia NEBS, CE and UL.
Applications Electronics enclosure designers are challenged by ever-shrinking footprints that force them to be creative in their thermal management solutions. Flex-Frame filters are ideal for use in air filter applications that require the filter to "snake" around jutting components or conform to a radius-type bezel. The Flex-Frame is designed for electronics equipment that cannot accept a rigid air filter frame because of internal chassis obstructions or the necessity to follow a curved track.
Specifications 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), and various thicknesses (.25 to 1.00 inches). Frame thicknesses range from .03 to .125 inches. A solvent-resistant, two-part epoxy bonding material is used to securely unite frame and filter media making them inseparable.
Media Cleanable black, gray or green Quadrafoam is specified for Flex-frame air filters. Quadrafoam is an open cell polyurethane foam specially coated to meet UL 94 HF-1. It features deep loading, large dust holding capacity and low air resistance.
Frame Black polypropylene is rated UL 94V-0. Frames are manufactured using an innovative "frame-n-pane" design that integrates the frame and a series of crossing, reinforcing intermediates that provide media support. Pane sizes and frame thickness are customized to the equipment's needs.
