Key Product Advantages

Deep-Pleated Media Balances Filtration Performance & Low Pressure Drop

Gradient folded glass fiber maximizes effective filtration area and optimizes internal airflow channels, maintaining stable low pressure loss under 24/7 full-load continuous operation, effectively cutting long-term power consumption of air compressor units.

Large Liquid Holding Capacity Extends Maintenance Intervals

Thick multi-gradient hydrophobic fiber matrix provides massive oil & water storage volume, resisting rapid saturation under medium-humidity workshop environments and reducing frequent replacement labor and spare parts costs for central air compressor stations.

Hydrolysis & Oil Resistant Structure Eliminates Secondary Pipeline Contamination

Oleophobic borosilicate glass fiber paired with stainless steel support mesh prevents fiber shedding, avoiding oil-dust secondary contamination to downstream pneumatic valves, spray guns and ordinary electronic assembly equipment.

Bayonet Quick Replacement Without Housing Modification

Overall length, outer diameter, top bayonet locking structure and sealing gaskets perfectly match original DD170 filter housings; single operator can complete cartridge replacement within minutes without full housing disassembly.

Working Principle

Dust-free pre-filtered compressed air flows outside-in through the filter cartridge:

Solid particles larger than 1μm are trapped and stored inside the fiber matrix;

Micro oil & water aerosols collide and coalesce into large liquid droplets via gradient glass fiber layers;

Outer blue anti-re-entrainment foam sleeve stops coalesced liquid from being re-carried by high-speed airflow;

Condensed oil and water drain down to the filter bowl by gravity;

Dry, low-oil compressed air is delivered to the subsequent activated carbon filter for deodorization and oil vapor removal.

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.
