Key Product Advantages

Integrated solid-liquid separation for general factory compressed air purification

Installed after PD360 particulate pre-filter, this DDP grade element simultaneously removes pipeline rust, dry dust, submicron oil mist and condensed water droplets that single dust filters cannot eliminate. Outer blue hydrophobic foam prevents secondary liquid re-entrainment, condensed oil & water drain quickly to filter bowl, supplying medium-clean compressed air for most standard pneumatic production lines.

Deep-pleated media balances filtration performance & low pressure drop

Gradient folded glass fiber expands effective filtration area and optimizes internal airflow channels, maintains stable low pressure loss under 24h full-load continuous operation, reduces long-term power consumption of large air compressor units.

Large liquid holding capacity extends maintenance intervals

Thick multi-gradient hydrophobic fiber matrix stores massive condensed oil and water, not easy to saturate in medium-humidity workshop environments, cuts frequent replacement labor and spare parts procurement cost for central air compressor stations.

Hydrolysis & oil resistant structure avoid secondary pipeline contamination

Working Principle

Dust-free pre-cleaned compressed air from PD particulate filter flows outside-in through multi-layer hydrophobic borosilicate glass fiber media:

Solid particles above 1μm are trapped inside fiber matrix;

Tiny oil & water aerosols collide and aggregate into large liquid droplets;

Application Industries

Large machining workshops, forging plants, textile integrated factories, packaging printing workshops, general automotive repair spray booths, group factory central air compressor stations, construction machinery air supply systems, full-automatic ordinary pneumatic production lines.
