Key Product Advantages

Third-stage ultra-fine polishing protection for downstream carbon filter

Installed after DD medium filter, this PD element captures invisible 0.01μm submicron oil mist that medium filters cannot separate. It greatly reduces oil load on QD carbon elements, extends carbon service life and cuts spare parts cost for small pneumatic systems.

Compact large dirt & liquid holding capacity

Deep pleated microglass media stores abundant oil and condensate within small size. Outer red drainage foam accelerates liquid gravity backflow, slows pressure rise and reduces frequent maintenance downtime.

Heat-stabilized media, no fiber shedding pollution

Heat-cured borosilicate microglass with double stainless steel mesh prevents glass powder from entering small-bore pipelines, protecting micro spray nozzles, tiny laser lenses and miniature solenoid valves from blockage.

Low permanent differential pressure saves compressor power

Uniform gradient pore layout keeps stable low backpressure throughout service life, lowering continuous load of small screw compressors and reducing factory electricity expenditure.

Working Principle

Pre-dried compressed air flows through cartridge outside-in:

Micro water droplets and fine solid impurities are trapped by outer red hydrophobic foam and drain to filter bowl by gravity.

0.01μm ultra-fine oil micro-aerosols collide and coalesce into large liquid droplets inside gradient microglass media.

Outer anti-re-entrainment foam stops separated oil from being re-carried by high-speed airflow.

Collected oil and water drain automatically via mini float drain valve.

Ultra-clean air with residual liquid oil ≤0.01 mg/m³ flows downstream to activated carbon filter for oil vapor removal.

Application Industries

Mini laser marking equipment, laboratory analytical instruments, portable small spray guns, cosmetic micro-filling lines, dental & medical small gas supply, miniature automation test benches, precision electronic workstation auxiliary air, small food aseptic packaging equipment.
