DP® Max extended surface, pleated air filters with Airguard® technology are suitable use in virtually any air handling system, including filter banks, central station air handlers, rooftop units, side access housings, as final filters for systems with MERV 8 or MERV-A 8-A requirements or pre-filters in multi-stage systems.The filters are manufactured using sophisticated production control techniques to ensure consistent pleat count, height, shape, and spacing, which contributes to better performance and longer service life. Predetermined pleat centers allow dirt to collect evenly over the entire surface of the media, resulting in a slow, steady rise in resistance to ensure maximum dust-holding capacity. The two-piece frame with double-wall thickness around the outer edge provides rigidity. This coupled with a die-cut pattern with 50% more contact points between the media pack and the frame, gives DP® Max filters superior durability for use in demanding environments, where harsh conditions often cause alternative filter products to fail prematurely. All DP® Max filters exceed ASHRAE Standard 52.2 air cleaning specifications for filters installed upstream of cooling coils. Filters may be installed with the pleats either vertical (preferred) or horizontal.Markets:Commercial and Industrial HVACProcess Air FiltrationApplications:Air handling systemsRooftop unitsSide access housingsBuilt-up filter banksPre-filters in multi-stage systemsBenefits:Exceeds American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 52.2 air cleaning specifications for filters installed upstream of cooling coils100% thermally bonded synthetic, proprietary media resists moisture, delaminating, excessive buckling, collapsing, warping, and bendingAvailable in a wide range of sizes and air flow rates to meet the unique requirements of customers’ systemsLow initial resistance facilitates efficiency and energy savingsResistant to mold and microbial growthPerforms to MERV 8 and MERV-A 8-A before and after a conditioning step Features:Filtration efficiency: MERV 8, MERV-A 8-ANominal thickness (in.): 1, 2, 4, 6Rated air velocity (fpm): 300–625Air flow rates (cfm): 210–3,640Initial resistances (in.w.g.): 0.16–0.21Final resistance (in.w.g.): 1.0Maximum operating temperatures: 225 °F (107 °C) Material of construction: moisture-resistant beverage board frame; rust-resistant, expanded metal support grid made of galvanized steelClassified per UL Standard 900 for flammability
