Key Product Advantages

Dual-stage high-efficiency oil interception to guarantee ultra-low residual oil air output

Multi-layer gradient glass fiber coalescing media captures micro oil mist generated during screw compression. Separated lubricating oil flows back to the compressor lubrication circuit automatically, limiting residual oil content of compressed air below 3 ppm, effectively protecting downstream precision filters, refrigerated dryers, adsorption dryers and terminal pneumatic equipment.

Super-large oil holding capacity, stable long-cycle continuous operation

Deep-pleated composite fiber structure expands effective separation surface area and oil storage volume, resisting rapid pressure rise under 24/7 heavy-load continuous operation; perfect for non-stop industrial central compressor stations.

High temperature & hydrolysis resistant media, no fiber shedding risk

Heat-stabilized integrated glass fiber composite avoids aging under long-term 120°C hot compressed air impact, no fiber detachment to prevent secondary pipeline contamination, spray gun blockage and pneumatic valve failure.

All-in-one spin-on design for fast maintenance

Integrated metal top end cap + built-in sealing ring, direct screw installation outside the compressor separator tank; a single operator completes full replacement within 5 minutes without complicated tank disassembly.

Working Principle

Mixed air-oil mixture flows through the separator cartridge from outside to inside:

Large oil droplets collide and coalesce on the outer coarse fiber layer, flow down to the tank bottom by gravity;

Invisible submicron micro oil mist is captured and condensed into large liquid droplets via multi-layer gradient glass fiber media;

Separated clean lubricating oil flows back to the compressor lubrication system through central oil return hole;

Low-oil clean compressed air flows out from inner core to post-treatment filtration pipelines.

Application Industries
