Defiant Cell Filters - Construction

Defiant Cell™ medium and high-efficiency rigid box filters prolong life cycles. The unique patented non-woven process used to manufacture Defiant Cell™ box filters creates media that outperforms similar products with respect to initial efficiency, average efficiency, and dust holding capacity.

The continuous hydrophobic fibers that make up Defiant Cell™ box filters do not absorb moisture and are thermally bonded to eliminate the need for chemical containing binders that could promote microbial growth or generate VOCs. Defiant Cell™ filters are able to withstand turbulent, high velocity conditions, even when high humidity is a factor.

Fire Resistance - 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 and 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.
