Key Product Advantages

Ultra-high coalescing efficiency reduces load on downstream pipeline precision filters

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

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

Extra-deep pleated microglass matrix stores massive oil sludge, carbon deposits and fine solid impurities without rapid pressure rise, suitable for non-stop heavy-duty workshop operation.

Heat-stabilized glass fiber media prevents fiber shedding and system secondary pollution

High-temperature cured borosilicate media will not soften, deform or pulverize under sustained 105℃ oil-gas mixing temperature. No glass fiber debris enters air piping to block solenoid valves, spray nozzles or laser optical lenses.

Low permanent differential pressure saves compressor power consumption

Uniform gradient pore layout maintains minimal airflow resistance throughout the full service cycle. Stable low backpressure reduces continuous running load of the main motor and cuts long-term factory electricity costs.

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 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 piping;

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