Key Product Advantages

Ultra-high coalescing efficiency reduces contamination load of downstream pipeline precision filters

Multi-layer gradient glass fiber media traps micro oil aerosols generated during screw compression. It drastically cuts oil pollution entering refrigerated dryers, medium/ultrafine coalescing filters and activated carbon adsorbers, extends service life of all downstream consumables and lowers overall factory maintenance expenditure.

Large oil & dirt holding capacity supports long-hour full-load non-stop production

Extra deep-pleated microglass matrix stores massive oil sludge, carbon deposits and fine solid impurities without rapid pressure rise, perfectly matching continuous heavy-duty workshop operation.

Heat-stabilized glass fiber media avoids fiber shedding and secondary system contamination

High-temperature cured borosilicate media remains stable under sustained 105°C oil-gas mixing temperature, no softening or pulverization. Zero glass fiber debris enters air pipelines to block solenoid valves, spray nozzles and laser optical lenses.

Low permanent differential pressure design cuts compressor power consumption

Uniform gradient pore layout maintains minimal airflow resistance throughout the full service cycle. Stable low backpressure decreases continuous load of the main motor and slashes long-term workshop electricity expenses.

Integrated flange one-step replacement design

Complete set with matched sealing O-ring. A single technician completes replacement within 5 minutes after machine shutdown, full pressure relief and oil tank venting; no separate loose gaskets to cause assembly leakage.

Working Principle

High-temperature mixed oil-gas flow passes through the separator cartridge from outside to central inner core:

Large oil droplets collide with outer perforated galvanized support mesh, coalesce and drain back to the compressor oil tank via gravity;

Submicron oil aerosols are captured layer-by-layer by gradient microglass media, merge into large liquid oil droplets and flow downward for recovery;

Dry compressed air with residual oil below 3 ppm flows through the central tube to post-processing air pipelines;

All trapped sludge and solid contaminants are locked inside separator media to prevent secondary circulation pollution of the lubrication system.

Application Industries

Automotive component manufacturing workshops, plastic injection molding factories, metal cutting & welding production lines, pharmaceutical packaging plants, food processing factories, mining pneumatic equipment air supply stations, electronics assembly workshops, medium electrostatic spray booth air supply systems.
