Key Product Advantages

Large-flow integrated aluminium filter housing for 25 m³/min air systems

One-piece cast aluminium structure with uniform wall thickness, stable pressure resistance, lightweight and anti-rust compared to steel vessels; standard 2" large port reduces airflow resistance for medium-large compressor stations.

Quick bayonet cap maintenance design, single-person operation

No special tools required; release top two fixing bolts to lift the cap, extract old cartridge and install new element within 5 minutes, greatly cutting production downtime during maintenance.

Full anti-corrosion & static safety design

Epoxy coated aluminium housing resists acidic condensate and humid factory environments; static conductive cartridge media eliminates static discharge risk in oil-air mixed pipelines, avoiding hidden fire hazards.

Universal aftermarket interchange compatibility

76090 series cartridges fully interchangeable with mainstream domestic filter brands, low spare part procurement cost, compatible with automatic drain valves and differential pressure indicators of multiple brands.

Working Principle

Removing fine dust and submicron oil mist penetrates multi-layer gradient glass fiber media; tiny liquid particles collide, aggregate and coalesce into continuous liquid film for gravity drainage.

After graded purification by multi-stage cartridges, high-purity compressed air flows downstream to dryers, production equipment and precision pneumatic terminals.

Cartridge cannot be cleaned or regenerated on-site. Once saturated with oil sludge and dust, differential pressure surges and separation efficiency fails, requiring full cartridge replacement.

Application Scope

Automotive painting workshops, heavy metal fiber laser cutting factories, large plastic injection molding lines, food & beverage sterile packaging pneumatic systems, textile mill central compressed air supply, pharmaceutical aseptic production gas pretreatment, large precision electronic cleanroom gas supply.
