The Super-Flow®24 can be incorporated into systems with air velocities of 600 fpm and a pressure drop of 1.0-inch w.g. Product Design The Super-Flow®24 filters are manufactured with wet laid microfine fiberglass media. The media is formed into a minipleat utilizing a hot melt separator and arranged in a V-bed configuration. There are twelve individual minipleat packs sealed on all four sides to the frame with two-component polyurethane. The frame is constructed of 20 ga. galvaneal, aluminum or stainless steel and consists of vertical support struts of the same material. Vertical supports are attached to the frame body without the use of mechanical fasteners. The vertical supports act as the sealing surface of the mini pleat packs. Product Options The Super-Flow®24 are available in aluminum, galvaneal or stainless steel frames and with gasket seal or gel seal design. The Super-Flow®24 filters are UL 900 Class 2 listed. • Gasket Seal The filter gasket is 1/4" x 3/4" black neoprene attached to the frame with an adhesive and the gasket joints are dovetailed to ensure no penetration of particulate due to the gasket. The filter is designed for installation into Flanders front load B-1 holding frame, C-3 Gasket Seal Housing and Surelock-B Side Access Housing. • Gel Seal The filter gasket is Flanders Blu Jel® filled into a channel around the perimeter of the frame. The gel seal design provides the highest degree of sealing integrity between the filter and holding device. The filter is designed for installation into Flanders front load A-4 holding frame or C-4 Gel Seal Housings. Important Features The product offers the following advantages over conventional HEPA filters. • Longer Life Gasket seal Super-Flow®24 filters have 400 sq. ft. of media compared to 240 sq. ft. for traditional HEPA filters. The greater media area provides a longer time period between filter replacements. • Improved Efficiency The significant quantity of media translates into an extremely low media velocity. Therefore a minimum overall efficiency of 99.99% at 0.30 .m is easily assured. Traditional HEPA filters have an overall efficiency of 99.97% at 0.30 .m. • Lower Operating Cost The typical HEPA filter pressure drop can range from 1.4-inch w.g. to 1.8-inch w.g. at the rated flow. The pressure drop of the Super-Flow®24 is 1.0-inch w.g. at the rated flow.
