Key Product Advantages

Installed after coarse prefilter, this GP-grade cartridge intercepts bulk condensed water, large oil droplets and 1μm oil mist, greatly reducing liquid contamination load on terminal high-precision filter elements, extending their service life and cutting spare parts cost.

Large dirt & liquid holding capacity for stable long-cycle operation

Thick deep-pleated microglass matrix provides high oil/water storage capacity; outer drainage foam accelerates liquid separation and gravity discharge, slowing pressure rise in humid workshop environments and reducing unplanned downtime from frequent filter replacement.

Heat-stabilized media, zero fiber shedding to avoid pipeline secondary pollution

Heat-cured borosilicate microglass composite combined with stainless steel support mesh prevents glass fiber powder shedding into pipelines, protecting precision spray guns, laser lenses and miniature solenoid valves from blockage failure.

Low permanent differential pressure to reduce air compressor energy consumption

Uniform gradient pore structure minimizes airflow resistance throughout service life; stable low backpressure lowers continuous power consumption of medium screw compressors and reduces long-term electricity cost.

Working Principle

Preliminarily filtered compressed air flows from outside to inside the cartridge:

Residual large water droplets and fine solid impurities are trapped by outer red hydrophobic foam, draining down to filter bowl via gravity;

1μm oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient microglass media;

Outer anti-re-entrainment foam prevents separated liquid droplets from being re-carried by high-speed airflow;

Collected oil and condensate are automatically discharged by electronic float drain valve;

Medium-clean dry air flows downstream to HE ultrafine filter for further precision polishing.

Application Industries

Medium automotive spray booths, laser marking/cutting equipment, textile printing, packaging automation lines, standalone medium screw compressor stations, plastic injection molding auxiliary air, general pneumatic tools, laboratory analytical instruments, small food processing auxiliary gas supply.
