Use CPI Filter Fans to propel the cool ambient air into the enclosure. For intake fans, once installed, a slight positive pressure builds up inside the cabinet, so that only air filtered by the Filter Fans flows into the enclosure. The patented click mechanism on the Filter Fans have a unique four-corner fastening system that enables safe and quick, tool-less installation, maintains the rated seal, and allows the filter medium to be replaced in seconds.
