Windowpane air filters are the ideal solution to meet the low profile and edge-to-edge filter needs of communications
electronics applications. Windowpanes help
telecom/datacom electronics designers meet the stringent requirements of the Telcordia NEBS standards. The special design creates a sturdy air filter even when the combined thickness of filter media and frame is as thin as ¼" for applications where space is limited.
Specifications Universal Air Filter can customize Windowpane filters to meet Telcordia Standards for telecommunications and data communications equipment. Filters are designed to meet:
- "GR-63-CORE, Network Equipment Building System (NEBS) Requirements : Physical Protection, Environmental Criteria, Issue 2, April 2002."
This guideline specifies UL 94 HF-1 filter media flame rating, minimum 80% dust arrestance, and UL 900 Class 2 framed filter fire rating.
- "GR-78-CORE, Generic Physical Design Requirements for Telecommunications Products and Equipment, Issue 3, December 1991."
This guideline specifies minimum 80% dust arrestance and UL 900 Class 2 framed filter fire rating.
Media
Cleanable black, gray or green Quadrafoam is specified for Windowpane 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. Quadrafoam is available in various pores per inch (PPI) ranging from 10 through 60 PPI.
Frame
Windowpane air filters maintain necessary rigidity, keeping their shape and staying in place with 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.
