DuraMAX V-Style Minipleat Filter The DuraMAX is a rigid, extended surface air filter, engineered to provide maximum performance and prolonged filter life cycles, even in the most difficult environments. The durable, rugged, construction of the DuraMAX make it the filter of choice in filtration systems with high velocities or variable air volumes. DuraMAX Filters are constructed with a 100% plastic frame and are completely incinerable. DuraMAX provides an unequaled combination of low pressure drop and high efficiency through the use of our unique minipleat design. This high capacity minipleat design allows a nominal 24x24x12 filter to incorporate 194 square feet of filter media. This increased extension of the media surface area insures low pressure drop, and low resistance to airflow means lower energy costs to the user. Another benefit of the increased media area is extremely high Dust Holding Capacity, which significantly prolongs the service life of the filter. Fewer filter changes translate into substantially reduced maintenance and disposal costs. In order to meet the wide range of requirements found in today's complex air filtration systems, DuraMAX filters are available in five ASHRAE efficiencies, 65, 75, 85, 95, and 98%. The Filter is offered in three standard sizes, 24x24x12, 20x24x12, and 12x24x12. Single or double header configurations are available.
