The CR-series filter is a big, round filter that handles large volumes of air. It has a continuous reverse-air cleaning system and is rated up to 50,000 cfm. It features top-bag-removable filters with a walk-in clean air chamber. A unique air inlet removes dust prior to entry into the filter, extending filter bag life. Air is evenly distributed to all filter bags with internal baffles.Kice Industries Inc., Wichita, KS 316-744-7151 www.kice.com
