Windowpane Air Filters

Windowpane filters are a low-profile solution for any industry application requiring frames constructed from a variety of metal materials, one piece frames with built-in handles or captive fasteners, L-shaped frames,  or bezel + filter combinations.

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 5, December 2017.” This guideline specifies UL 94 HF-1 filter media flame safety rating, minimum 80% dust arrestance, UL 900 Classification marked frames, and framed air filter requirements.

Framed Filters: +/-.03″ length & width, +/-.03″ thickness

Quadrafoam™ filter media is available in all frame models in various pore sizes (10 through 80 PPI Gray and Black).

Quadrafoam II™ filter media is available in all frame models in various pore sizes (10 through 45 PPI Gray and Black).

Unifoam filter media is available in all frame models in various pore sizes (10 through 80 PPI Black).

Quadrafoam™ and Quadrafoam II™ are open cell polyurethane foams specially coated to provide a UL 94 HF-1 flame safety rating, fungus resistance, and UV radiation resistance. They feature deep loading, high dust holding capacity and low air flow resistance for use in extremely wide climatic conditions.

Unifoam is an open cell polyurethane foam specially formulated to provide maximum air flow and meet UL 900 Classification.  The random arrangement of strands and pores make this a filter media with tremendous dust-holding capacity and arrestance.

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 and can include extended surface designs for more air flow, lower pressure drop, and increased dust holding.

Frames can be constructed from a variety of metal materials, designed as one-piece frames with built-in handles or captive fasteners, L-shaped frames,  or bezel + filter combinations.
