Air Filter Rolls for Automatic Roll Machines
Replace the filter roll in your automatic filtering equipment. The filter is wrapped onto a core; use the pull tabs for installation. Made of polyester, they capture more particles than fiberglass rolls. These rolls meet UL Classified flame retardance requirements.
