DEFIANT Mark80 - Heavy Duty - 1 Inch Pleated Filter (DMK80HD) 5257687691

DEFIANT® Mark80-HD pleated air filters from Purolator® are designed for use in challenging HVAC and process filtration applications. Max. flow rates: 585 – 2,085 cfm depending on size (1-, 2-, or 4-in). Achieves MERV 9 before and after conditioning.

The Purolator® DEFIANT® Mark80-HD pleated air filters’ heavy-duty media, die-cut frame and corrosion-resistant wire backing construction enable them to operate in the most demanding HVAC and process applications, where elevated moisture conditions and high amounts of airborne dust often cause conventional air filters to delaminate, buckle, collapse, rack or warp.

The filters are manufactured using sophisticated production control techniques to ensure consistent pleat count, height, shape, and spacing. This uniform spacing contributes to a better-performing pleat with low pressure drop, full-depth dust loading, and 4X times longer service life than standard commercial high-capacity pleats. The 4-in. thick filters feature two sets of pleat stabilizers (fingers) inserted to maintain proper pleat separation and reduce fluttering in operation.

The proprietary media consists of 100% hydrophobic (water repellant) polyester fiber. The pleated media pack is contained within a frame made with two pieces of 27-point heavy-duty die-cut beverage board with high wet-strength characteristics. Diagonal support members are an integral part of the die-cut pieces, providing support for the media pack on both sides. The two mating pieces of the die-cut frame fully overlap the entire perimeter of the filter. Frame corners include interlocking flaps to provide additional strength and eliminate bypass in the corners.
