Kaeser Compressor Filter Mats are high-quality air intake pre-filters designed to protect the internal components of the compressor cabinet and the main cooling system from airborne dust and debris. Typically installed on the cabinet doors or cooling air inlets of ASD, BSD, and CSD series compressors, these mats act as the first line of defense, preventing the clogging of the Combi Cooler fins and the electric motor’s ventilation system. Manufactured from specialized, non-migrating synthetic fibers with a high dust-holding capacity, genuine Kaeser filter mats ensure that the internal cabinet temperature remains stable and the cooling airflow remains unrestricted. Regularly replacing these mats is a cost-effective way to prevent the compressor from overheating, reduce the load on the cooling fan, and extend the service life of the more expensive internal air and oil filters.
