Key Product Features

Two-Stage Deep Coalescing Oil Separation

Outer coarse fiber layer intercept large oil droplets for primary gravity sedimentation; inner ultra-fine glass fiber coalesces invisible micro oil mist into recoverable liquid oil, drastically reducing oil carryover into post air pipeline filters, lowering compressor lubricant consumption.

Ultra-Low Initial Pressure Drop & Energy Saving

Large deep-pleated filter area minimizes airflow resistance inside the oil tank. Avoids excessive backpressure that raises motor load, cutting long-term electricity operating cost of the air compressor host.

High Oil & Sludge Holding Capacity

Thick gradient fiber matrix stores massive coalesced lubricant oil and metal wear sludge, extending maintenance intervals and reducing frequent machine shutdown replacement.

Rigid Anti-Deformation Metal Reinforcement

Dual galvanized steel mesh cages resist violent turbulent airflow inside the oil tank, preventing media bulging, collapse and fiber shedding to avoid secondary contamination of post-processing filters and terminal equipment.

Working Principle

Air-oil mixed aerosol discharged from compressor rotor flows into separator core from outer mesh. Large oil droplets are blocked and fall back to oil sump directly; invisible submicron oil mist penetrates multi-layer glass fiber media, collides and aggregates into large liquid oil beads. Collected oil flows down through built-in central siphon tube and returns to compressor oil tank by gravity. Dry low-oil compressed air flows out from central pipe to pipeline pre-filter system.

Application & Industries

Built-in primary oil separation component for medium-flow oil-injected screw air compressors.

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