• The Q Cell Final Filter has deep “V” pleats to maximize exposure to air for even dust holding capacity. The pleats are tapered to channel air through the filter. The Q Cell Final Filter is made with 26 gauge galvanized steel for maximum rigidity and to resist corrosion. Plastic separators prevent blowout or the bowing of the pleat packs. The filter media is synthetic and resistant to moisture, abrasion, and microbial growth. The Q Cell Final Filter comes in a variety of efficiencies for your specific application.
