Product Information

The Defiant-CellTM is a rigid box air filter engineered to provide medium and high-efficiency filtration combined with a prolonged life cycle. The unique, patented non-woven process used to manufacture DEFIANT Cell filters creates a media which outperforms similar products with respect to initial efficiency, average efficiency, and dust holding capacity.

Fire Resistance - All DEFIANT Cell rigid box filters are classified per UL Standard 900 for flammability. The maximum operating temperature for these filters is 180oF.

Improved Efficiency - DEFIANT media utilizes a dual-stage electrostatic enhancement, and continuous fiber structure to initially capture an increased amount of smaller particulate than conventional glass media–thereby improving overall particle size efficiency.

Applications - DEFIANT Cell 70/85/95 media box filters are specifically manufactured for industrial/commercial HVAC system applications requiring constant or Variable Air Volume (VAV) systems. This product provides 20 - 30% improved dust holding capacity and efficiency beyond that of competitive products. The DEFIANT Cell 70/85/95 media has multiple performance characteristics which combine to provide optimum filter service life, and lower maintenance and energy costs.
