Key Product Advantages

Second-stage compact medium polishing barrier to protect downstream PD45 ultrafine filter and QD45 carbon filter

Installed after primary coarse pre-filter, this DD-grade element intercepts bulk condensed water, large oil droplets and 1μm oil mist. It drastically reduces liquid contamination load on downstream high-precision filter elements, extends their service life and cuts spare parts costs for small pneumatic equipment.

Miniature high dirt and liquid holding capacity for limited-space installation

Compact deep-pleated microglass matrix holds sufficient volumes of oil and condensate within tiny dimensions. The outer blue drainage foam accelerates liquid separation and gravity backflow, slowing pressure rise in small workshop air loops and reducing unplanned downtime caused by frequent filter replacements.

Heat-stabilized media, zero fiber shedding to avoid small-bore pipeline secondary contamination

Heat-cured borosilicate microglass composite paired with stainless steel support mesh prevents glass fiber powder shedding into thin-diameter air piping, protecting micro spray nozzles, tiny laser optical lenses and miniature solenoid valves from clogging failures.

Optimized low permanent differential pressure to reduce small compressor power consumption

Uniform gradient pore layout minimizes airflow resistance throughout the entire service cycle. Stable low backpressure lowers continuous load of mini screw compressors and portable air pumps, cutting long-term factory electricity expenses.

Working Principle

Pre-filtered compressed air flows through the cartridge from outside to inside:

Residual large water droplets and fine solid contaminants are trapped by the outer blue hydrophobic foam and drain into the mini filter bowl via gravity.

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

The outer anti-re-entrainment foam prevents separated liquid oil from being re-carried by high-speed compact compressed airflow.

Collected oil and condensate are discharged automatically via mini float drain valve.

Medium-clean dry compressed air flows downstream to the PD45 ultrafine coalescing filter for further precision purification.

Application Industries

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