Key Product Features

Two-Stage Deep Coalescing Separation

Outer coarse fiber layer intercepts large oil droplets for primary gravity sedimentation; inner ultra-fine glass fiber coalesces invisible micro oil mist into recoverable liquid oil. It effectively cuts lubricant consumption and prevents rapid saturation & premature failure of downstream pipeline precision filters.

Ultra-Low Initial Differential Pressure & Energy Saving

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

Large Dirt & Oil Holding Capacity

Thick gradient fiber matrix stores massive coalesced lubricant oil, metal wear debris and sludge contaminants, extending maintenance intervals and cutting production downtime caused by frequent element replacement.

Rigid Anti-Deformation Reinforcement Structure

Dual metal protective mesh cages resist violent turbulent airflow inside the oil tank, preventing media bulging, rupture and fiber shedding to eliminate secondary contamination of post-processing air equipment.

Working Principle

Oil-air mixed aerosol discharged from the compressor rotor enters the separator cartridge from the outer metal mesh. Large oil droplets are blocked and fall back to the oil sump directly. Remaining micron-sized oil mist penetrates multi-layer glass fiber media; tiny oil droplets continuously collide and aggregate into liquid oil beads, which flow down the inner wall by gravity and return to the compressor oil tank via the built-in bottom oil return tube. De-oiled clean compressed air flows out through the central pipeline to refrigerated dryers and precision filtration systems.

Application & Industries

Built-in primary oil separation core for medium-power oil-injected screw air compressors.

Widely used in machinery processing, automotive workshops, spray coating lines, laser cutting equipment, packaging & printing factories, textile plants, food processing and centralized factory compressed air supply stations.
