Air Pre-Filter Mat (also known as a filter media roll or pad) is the critical first stage of defense for industrial air compressors and electrical cabinets. Designed to capture large airborne particles such as lint, hair, pollen, and heavy dust, these mats are typically installed over the cabinet air intake or the secondary intake of the compressor. By acting as a "sacrificial" barrier, the pre-filter mat significantly extends the life of the expensive primary air intake filter and prevents the internal cooling fans and oil coolers from becoming clogged with debris. Manufactured from high-quality, non-woven polyester fibers with a graduated density structure, these mats provide high dust-holding capacity while maintaining maximum airflow.
