52553021 Industrial Air Compressor Air Filter Element – Enhanced Contamination Protection for Compressor Reliability

Engineered to shield industrial compressors from fine, wear-causing debris, the 52553021 delivers 99.9% filtration efficiency at ≥1.0 microns, trapping dust, oil aerosols, and metal fines that degrade pistons, clog valves, and foul air dryers—vital for manufacturing, mining, or high-dust sites where uptime drives productivity.

Built with a multi-layer synthetic media (anti-static microglass + electrostatic retention) and a corrosion-proof galvanized steel housing (epoxy-polymer coated), it resists pressures up to 28 bar and temperatures from -42°C to 123°C. This design thrives in harsh environments—steel mills, coastal plants, or dusty workshops—withstanding vibration, humidity, and chemical exposure.

The pleated structure holds 390g of contaminants, lasting 1,750+ operating hours (50% longer than standard)—cutting replacement downtime and labor costs. Universal fit for 12–65 HP compressors (Atlas Copco GA 15–25, Ingersoll Rand R7–16i, Sullair LS 15–30), it features tool-free bayonet installation in <5 minutes for easy maintenance.

Lowers total cost of ownership: Reduces motor strain by 9% (cleaner air = less energy) and extends downstream dryer/actuator life by 60%. Backed by a 12-month warranty and 24/7 support, the 52553021 ensures your compressor runs clean, efficient, and reliable—protecting your investment and boosting output.
