Key Product Advantages

Two-Stage Deep Precision Coalescing Separation

The matched 755 primary outer core removes large oil droplets via primary gravity sedimentation; this 756 secondary inner core captures invisible ultra-fine oil mist. It drastically reduces lubricant consumption and protects downstream pipeline precision filters from rapid oil saturation and premature failure.

Low Initial Differential Pressure & Energy Saving

Large pleated filtration area minimizes airflow backpressure inside the oil tank, avoiding increased motor load and steadily cutting long-term power consumption of the air compressor.

Ultra-Large Dirt & Oil Holding Capacity

Thick gradient glass fiber matrix holds massive coalesced lubricant oil and metal wear debris, extending maintenance intervals and reducing costly production downtime for element replacement.

Heavy-Duty Stainless Steel Reinforced Support Cage

Resists violent turbulent airflow inside the oil tank, preventing media bulging, rupture and fiber shedding to eliminate secondary contamination of downstream air equipment.

Working Principle

Oil-air mixed aerosol discharged from the compressor rotor first passes through the outer 755 coarse separator core, where large oil droplets fall back to the oil sump directly. Remaining micron-sized oil mist penetrates the multi-layer glass fiber medium of 756. Tiny oil droplets continuously collide and aggregate into liquid oil beads, which flow down the inner wall of the cartridge by gravity and return to the compressor oil tank via the built-in bottom oil return siphon tube. De-oiled clean compressed air flows out through the central pipe to refrigerated dryers and precision filtration pipelines.

Application & Industries

Primary oil separation component for medium & large oil-injected screw air compressor air supply systems.

Widely applied in machinery processing, automotive manufacturing, spray coating production lines, laser cutting, packaging & printing, food & pharmaceutical industry, textile factories and centralized factory compressed air supply stations.
