Max Operating Pressure: 1.6 MPa

Operating Temperature Range: 2℃ ~ 65℃

Initial Pressure Drop: ≤0.008 MPa

Replacement Alarm Differential Pressure: ≥0.05 MPa

Net Weight: 0.14 kg

Application Scenarios

Front pretreatment of small compressed air purification systems, general workshop pneumatic tools, casting & machining workshops with heavy dust, pre-protection for refrigerated air dryers, extend service life of downstream high-efficiency coalescing and activated carbon fine filters

Product Features

Outer hydrophobic foam sleeve blocks separated liquid water and oil from re-entering airflow, greatly improving gas-liquid separation efficiency. High dirt-holding gradient glass fiber media intercept most coarse contaminants to slow clogging of rear precision filters.

Ultra-low initial pressure drop deep-pleated design, minimizing long-term system energy loss and electricity consumption.

Integrated EPDM rubber sealing ring with excellent high temperature and aging resistance, effectively preventing pipeline air leakage.

Standard top plug-in installation for quick tool-free replacement, cutting maintenance downtime.

Each cartridge passes strict factory tests including dirt holding capacity, liquid separation efficiency and differential pressure cycling for stable long-term pretreatment performance.

Product Description

It removes large-particle rust, sand dust, bulk condensed water and coarse oil droplets from raw compressed air, effectively prolonging the service life of secondary coalescing and activated carbon filters, lowering overall maintenance frequency and cost of the whole air supply system.
