Gast AC393 Replacement Filter Cartridge

Product Description

The GAST AC393 is a replacement filter cartridge designed for use with the AC432 filter assembly on GAST air compressors and vacuum pumps. It maintains clean airflow by trapping particulates before they enter or exit the pump, protecting internal components and extending service life. The cartridge measures 2.75 inches in height and 2 inches in diameter, making it a compact, direct-fit replacement. Installation requires no special tools and is suited for scheduled maintenance intervals. HVAC technicians, industrial service personnel, and equipment maintenance pros typically handle this replacement as part of routine pump upkeep.

This filter cartridge fits systems where the AC432 assembly is installed. It is appropriate for both light commercial and industrial applications where GAST air compressors or vacuum pumps are used. The AC393 is sold as a single-piece unit, making it easy to stock and swap during planned maintenance without downtime beyond what is needed for a straightforward cartridge exchange.
