The Durafil ES is available in four standard efficiencies, which are MERV 11, 13, 14, and 16. The media is water-resistant and includes glass filament separators for uniform airflow throughout the media pack.
It incorporates a unique sealant channel to ensure a media pack-to-frame bonding to prevent air bypass. The unit comes in an impact-resistant plastic enclosing frame with modular plastic media pack supports, making a rigid and durable filter. This filter includes a one-inch header for added stability and a secure fit into the filter holding mechanism. The header is an integral component of the frame.
The Durafil ES also contains a header sealing gasket to ensure no air bypass between headers in multi-filter systems and to offer a bi-directional airflow. The unit can serve systems with airflow capacities up to 3,000 cfm. It has a maximum recommended final pressure drop capability to 2.0" w.g. and is guaranteed to 10" w.g.
The Durafil ES has been qualified by Underwriters Laboratories as UL 900 - Class 2. It is available with dual headers.
