Key Product Advantages

Two-stage high-efficiency oil interception to maintain ultra-low residual oil compressed air

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

Super-large oil holding capacity, stable long-cycle 24/7 continuous operation

Deep-pleated composite fiber structure expands effective separation surface area and oil storage volume, resisting rapid pressure rise under heavy-load non-stop running; perfectly suited for industrial central compressor stations with uninterrupted production schedules.

High temperature & hydrolysis resistant media, zero fiber shedding risk

Heat-stabilized integrated glass fiber composite avoids aging and powder detachment under long-term 120°C hot compressed air impact, eliminating secondary pipeline contamination, spray gun blockage and precision pneumatic valve failure caused by glass fiber debris.

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

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

Reduce compressor energy consumption & extend service life of post-treatment inline filters

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 tank bottom by gravity;

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

Application Industries

Automotive manufacturing spray workshops, metal machining factories, textile printing plants, packaging automation lines, medium laser cutting equipment, food & beverage aseptic production lines, plastic injection molding workshops, construction machinery supporting air supply systems.
