A Complete Line of Internally-Supported Panel Filters

Progressively dense, moisture resistant synthetic filter media provides optimum combination of efficiency, dust holding capacity and low pressure drop.

Heavy-duty, 9-gauge steel internal support wire with center cross wire provides rigidity and allows for easy installation.

Heat seal welds (in perimeter and center of filter) prevent media vibration during use. Filters may be installed vertically or horizontally.

Self sealing gasket design eliminates air bypass and allows for installation with no clips or latches.

Specialized, non-migrating tackifier improves efficiency and dust holding capacity.
