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

The durable and rugged construction makes the DuraMAX 4vS an ideal choice for filtration systems with high velocities or variable air volume (VAV) applications. It features an all-plastic frame that allows for easy incineration after use.

Low Pressure Drop Reduces Energy Costs

The DuraMAX 4vS delivers an unmatched combination of low pressure drop and high efficiency through its unique minipleat design. A standard 24 x 24 x 12 filter incorporates approximately 194 square feet of media, increasing the surface area and reducing airflow resistance, which helps lower energy costs.

Extended Filter Life

The increased media area results in exceptionally high dust holding capacity, significantly extending the service life of the filter. Reduced filter replacement frequency leads to lower maintenance and disposal costs.

Engineered Versatility

To meet the wide range of requirements in modern air filtration systems, DuraMAX filters are available in five ASHRAE efficiency levels (65%, 75%, 85%, 95%, and 98%). The filter is offered in standard sizes such as 24 x 24 x 12, 20 x 24 x 12, and 12 x 24 x 12, with options for single or double header configurations.
