Key Product Advantages

Core oil separation component to protect downstream pipeline filters and reduce compressor oil consumption

Installed inside the air receiver tank, this separator captures massive fine oil mist generated during screw compression. It drastically cuts oil carryover into post-treatment compressed air pipelines, reduces oil replenishment frequency, and extends service life of downstream medium coalescing filters, ultrafine coalescing filters and activated carbon elements.

High oil holding capacity for stable long continuous operation

Thick deep-pleated gradient microglass matrix stores large volumes of captured lubricant oil. Built-in drainage foam accelerates gravity oil reflux back to the compressor oil sump, slowing pressure rise and reducing unplanned compressor downtime caused by frequent separator replacement.

High-temperature stabilized media, zero fiber shedding to avoid downstream pipeline contamination

Heat-cured borosilicate microglass composite paired with double steel support mesh prevents glass fiber powder shedding into compressed air pipelines, protecting industrial spray guns, laser optical lenses and precision miniature solenoid valves from clogging failures.

Low permanent differential pressure design to cut compressor power consumption

Uniform graded pore layout minimizes internal airflow resistance throughout the full service cycle. Stable low backpressure inside the tank reduces continuous load on the screw airend, lowering long-term factory electricity operating costs.

Working Principle

High-temperature air-oil mixed flow passes through the separator cartridge from outside to inside:

Large residual oil droplets are intercepted by outer drainage foam and flow back to the tank oil sump via gravity;

0.01μm ultra-fine oil micro-aerosols collide and coalesce into large separable liquid oil droplets while passing through multi-layer gradient borosilicate microglass media;

Separated oil flows down the media surface back to the compressor lubrication circuit; clean compressed air passes through the inner support tube and exits the tank to downstream pipeline treatment equipment;

Built-in anti-re-entrainment foam prevents separated liquid oil from being re-carried by high-speed compressed airflow inside the tank.
