Mark 80-D Filters - Construction
Defiant Mark 80-D - The industry standard for performance and value for over 30 years. Compare the performance and value of Defiant Mark 80-D pleats to other types of filters, including disposable panel filters, ring panels, pads and frames or permanent filters for efficiency, low resistance, high dust holding capacity, durability and price. The Defiant Mark 80-D line has lower resistance to air flow to aid in your energy savings goals and objectives.
Gain 1 Point toward LEED Certification - During the process of new construction, install MERV 8 filters at each return air grille for air handlers used during construction. Conduct a two-week building flushout with new air filters and 100-percent outdoor air prior to occupancy.
Mechanical Media - Defiant Mark 80-D pleated filters are made with 100% synthetic fibers providing mechanical efficiency to achieve a MERV 8 performance. Defiant Mark 80-D filters maintain a MERV 8 performance before and after a conditioning step. The MERV 8 media has a PVA (Ployvinyl Acetate) adhesive that is not affected by mold or microbial growth.
Heavy Duty Deverage Board Frame - Defiant Mark 80-D filters are framed in moisture resistant, sturdy frame material to stand up against rough handling, difficult service conditions, and also provide long service life. The new 7-strap die cut pattern increases contact points between the beverage board and die cut by 50%.
Two Piece Frame Construction - Double wall thickness around the outer edge and integral die cut cross members provide strength and rigidity. Defiant Mark 80-D filters will not crack, warp or bend under normal handling or operating conditions.
Pleat Stabilizers - The 4" deep filters are designed with individual die cut fingers that separate and stabalize each pleat. Consistent pleat alignment enhances dust holding capacity for longer service life.
Galvanized Steel Pleat Support Prevents Rust - The Purolator expanded metal pleat support grid is made of galvanized steel for maximum rust resistance. The metal grid maintains pleat shape and prevents fluttering in operation. Consistent pleat shape minimizes resistance and improves dirt loading characteristics throughout the life of the filter.
