Key Product Advantages

Efficient dual-stage oil interception to guarantee low residual oil air output

Multi-layer gradient glass fiber coalescing media captures micro lubricating oil mist generated during screw compression. It recycles separated oil back to the compressor lubrication circuit, reducing compressed air residual oil content to below 3 ppm, protecting downstream post-filter, dryer and terminal pneumatic equipment.

Large oil holding capacity, stable long-cycle operation

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

High temperature & hydrolysis resistant media, no fiber shedding

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

Integrated spin-on one-piece design, fast maintenance replacement

Integrated metal end cap + built-in sealing gasket, direct screw installation inside separator tank; single operator completes replacement within 5 minutes without complex disassembly.

Reduce compressor energy consumption & extend auxiliary filter service life

Low permanent differential pressure minimizes extra motor power loss caused by clogged separators; drastically cut oil mist load of rear compressed air precision filters, extending service interval of DD/QD/activated carbon elements and lowering overall factory maintenance cost.

Working Principle

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

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

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

Separated clean oil flows back to compressor lubrication system through central oil return tube;

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

Application Industries

General metal machining workshops, textile printing plants, packaging production lines, small-medium laser cutting equipment, food & beverage factories, construction machinery supporting air supply, plastic injection molding automation lines.
