Key Product Features

High-efficiency Air-Oil Coalescing Separation

Gradient layered glass fiber fully captures tiny oil mist mixed in high-temperature oil-gas mixture. Micro oil droplets collide and aggregate into large liquid oil, which flows back to the oil tank by gravity through built-in oil return pipe. It effectively reduces oil carryover rate, cuts compressor lubricant consumption, and avoids oil contamination of downstream pipeline, refrigerated dryer and terminal pneumatic equipment.

Low Pressure Drop Energy-saving Design

Uniform deep-pleated filter media expands effective filtration area significantly. It maintains stable low airflow resistance under long-term full-load continuous operation, eliminates extra power loss caused by high back pressure, and lowers overall operation cost of air compressors.

Extra Large Oil & Dirt Holding Capacity

Multi-depth gradient composite structure stores massive separated lubricating oil, carbon sludge and metal wear debris, prolongs maintenance intervals and reduces production downtime for filter replacement.

Double-layer Galvanized Steel Reinforced Mesh

Inner and outer perforated metal cages resist high-speed airflow impact, prevent filter media collapse, deformation and fiber shedding, eliminate secondary fiber pollution inside the compressor oil circulation system.

High-temperature Anti-leak Flange Sealing System

Heat-resistant composite flange gasket provides tight sealing after bolt fastening. Zero oil-air leakage under frequent temperature and pressure fluctuation, stable separation efficiency without attenuation in long-term operation.

Working Principle

High-temperature oil-gas mixture discharged from screw airend enters the separator tank and flows through the outer layer of oil separator core. Large oil droplets are separated by gravity at first; residual 0.1μm micro oil mist is intercepted and coalesced by gradient glass fiber media, aggregated into heavy liquid oil that drips back to the oil tank for circulating lubrication. Clean low-oil compressed air flows out from central channel to post-processing purification pipeline.

Application & Industries

Widely used in machinery manufacturing, automotive parts processing, packaging printing, textile factories, industrial spray painting, food processing, medium laser cutting and factory centralized air supply systems.
