SPECIFICATIONS

Specifications - Pleated panel filters

Type I MERV8, MERV8-A, high capacity/mechanical filtration The filter media shall be bonded to a sturdy water-resistant coated beverage board filter frame to fit industry standard size filter racks. The media surface shall be bonded to the frame to prevent any slumping or collapse of media.

Pleated filter media shall be provided with integral support to assure against structural failure with resulting loss in filter effectiveness and uniform spacing of pleats. Filter loading to the final air pressure resistance shall not reduce structural stability of the media to the filter frame or equipment rack resulting in bypass air or blow out of the filter. Filters shall have an expanded galvanized steel support bonded to the downstream side of the filter to maintain pleat uniformity.

The filter shall be listed or classified as for compliance with Underwriters’ Laboratories UL900 as to flammability.

The filter shall carry a MERV 8 and MERV 8-A performance rating in accordance with ASHRAE Test Standard 52.2.

Specifications – Box filters

Type III Extended surface filters – rigid type suitable for VAV systems

Style 1 - Pleated micro-fiberglass media Filters consist of a pleated micro-fiberglass media with a water-resistant binder in a ridged box design.

The filter frame and cell sides shall be constructed of minimum 26-gauge galvanized steel or other corrosion resistant material. Cell sides shall provide mechanical stability and rigidity. The filter shall maintain filter integrity and media support to a maximum air flow of 1968 CFM for 12” depth filters.

Filters shall have an Average Atmospheric Dust Spot Efficiency of (90-95%, 80-85%, 60-65%, 40- 45%) as determined by A.S.H.R.A.E 52.1-92 test method, and shall have a Minimum Efficiency Reporting Value of (15-14, 13-12, 11-10, 9-8) according to A.S.H.R.A.E 52.1-99 Filter shall be available in a single header or non-header design. Single header models shall be equipped with a single 0.88” header on upstream side. Non header model shall provide holes for front load filter banks.

The filter shall be listed or classified as for compliance with Underwriters’ Laboratories UL900 as to flammability.

Style 2 - 95% efficient MERV14 Extended Surface Minipleat type shall consist of molded high-impact plastic polymer top, bottom, and end posts, and rigid (high-impact plastic polymer, 26 Ga.

galvanized metal) vertical channels, into which individual pleated filter panel sections are inserted. The media filter packs shall be bonded to the frame assembly using a sealer to prevent air by-pass and strengthen durability. The filter media shall be a bi-directional microfiberglass formed into panel sections using mini-pleat construction and shall incorporate separators to maintain spacing and low resistance to air flow. Filter panel construction shall provide superior dust holding capacity and prevent fiber shedding.. Each filter shall have an Average Atmospheric Dust Spot Efficiency of 90-95%, as determined by the A.S.H.R.A.E. 52.1 and have a minimum burst pressure of 10" w.g. The filter shall be rated 14 as to Minumum Efficiency Reporting Value (MERV), according to ASHRAE Standard 52.2-1999 test method, at a rated air flow capacity of 2000 CFM at 500 FPM face velocity. The initial resistance shall not exceed 0.36" W.G.
