Max Working Pressure: 16 bar / 232 PSIG

Continuous Operating Temperature Range: 1.5℃ ~ 66℃

Standard Service Life: 4,000–8,000 operating hours or 12 months (whichever comes first); replace when differential pressure reaches 0.35 bar

Key Product Advantages

Deep-pleated glass fiber media maximizes effective filtration area and optimizes internal airflow channels to eliminate turbulence. Stable low pressure loss is maintained under 24/7 full-load continuous operation, cutting extra power consumption of air compressors and lowering long-term factory air supply costs.

Ultra-Large Dirt & Liquid Holding Capacity

Multi-gradient depth filtration matrix stores large volume of separated lubricant oil, condensed water and solid sludge. Maintenance intervals are significantly prolonged to minimize costly production downtime caused by frequent element replacement.

Heavy-Duty Reinforced Anti-Delamination Cage

Dual anti-rust metal mesh cages withstand violent high-speed turbulent airflow inside filter housing, preventing media bulging, rupture and fiber shedding to eliminate secondary contamination of clean compressed air.

Working Principle

Raw unpurified compressed air flows into the cartridge from the outer metal protective mesh. The outer coarse fiber layer traps large solid particles, liquid water and bulky oil droplets. Coarse oil mist is coalesced into heavy liquid condensate, which sinks to the filter housing bottom and drains automatically via the built-in float drain. Primarily purified compressed air flows forward to PE058AA high-efficiency coalescing filter for further trace oil mist removal.

Application & Industries

First-stage protective pre-filter for medium-flow industrial compressed air post-processing systems, installed upstream of high-efficiency coalescing filters and refrigerated air dryers.

Widely applied in machinery manufacturing, automotive workshops, packaging printing factories, textile plants, industrial spray coating, pneumatic tool stations, food primary processing, laser cutting and centralized factory compressed air supply stations.
