  • High efficiency microfiberglass or synthetic media
  • Low pressure drop
  • Reduced energy cost
  • 194 square feet of media (24x24x12)
  • Incinerable
  • Light-weight plastic, extremely rigid frame
  • Superior dust holding and prolonged filter life

The DuraMAX 4v is a rigid, extended surface air filter that is engineered to provide maximum performance and prolonged filter lifecycles, even in the most difficult environments.

Its durable, rugged construction makes it a great choice for filtration systems with high velocities or variable air volume (VAV). Constructed with an all plastic frame, it is easily incinerated after use.

Low pressure drop reduces energy costs. The DuraMAX 4v provides an unequaled combination of low pressure drop and high efficiency through the use of our unique minipleat design. This design allows a nominal 24 x 24 x 12 filter to incorporate 194 square feet of filter media. This increased extension of the media surface area ensures a low pressure drop, which can aid in lowering energy costs to the building owner.

An extended filter life means less maintenance. 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.

Meet today’s and tomorrow’s building needs. 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%). It’s also offered in three standard sizes (24 x 24 x 12, 20 x 24 x 12, and 12 x 24 x 12). Additionally, single or double header configurations are available.
