The Koch Filter DuraMAX 4v is a rigid, extended surface air filter, engineered to provide maximum performance and prolonged filter lifecycles, even in the most difficult environments. The durable, rugged construction of the DuraMAX 4v make it the filter of choice in filtration systems with high velocities or variable air volumes. DuraMAX 4v is constructed with an all plastic frame so it is easily incinerated after use. 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.
