Air Filters

Part No: 1629010302

Core Technical Specifications

Pre-Filtration Interception Capacity: Captures residual fine solid particles and liquid oil mist ≥0.01 μm

Core high-density coconut-shell granular activated carbon matrix, fully encapsulated anti-powder-shedding sealed construction

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 1.5℃ ~ 60℃

Inlet Air Prerequisite: Compressed air must pass refrigerated/desiccant dryer + DD45 medium filter + PD45 ultrafine filter; no free liquid oil droplets permitted at inlet

Standard Replacement Cycle

1,000 working hours / 12 months under clean low-oil-load industrial environments; shorten to 600–800 hours for dusty, high-humidity spray booth workshops. Mandatory replacement when oily odor appears downstream or differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.015 MPa

Mandatory replacement alarm threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

End Caps: Reinforced black PA polymer threaded locking head with small-area uniform flow diversion ribs

Seal System: Integral built-in single full-circle NBR nitrile rubber O-ring gasket, zero air bypass, resistant to aging caused by high-temperature compressor oil and acidic condensate

Key Product Advantages

Final-stage oil vapor elimination barrier to generate 100% Class 0 oil-free compressed air

DD and PD glass fiber coalescing filters can only separate liquid oil mist, while this QD carbon cartridge adsorbs invisible gaseous oil vapor that penetrates glass fiber media. It completely removes oily odor and organic volatile contaminants to protect miniature precision processing equipment and finished product quality.

Compact high-capacity encapsulated carbon matrix with stable extended service life

Uniform high-porosity coconut shell activated carbon filling provides sufficient adsorption storage capacity within tiny dimensions. The front microglass pre-layer intercepts residual liquid oil mist before contacting carbon core, avoiding premature carbon poisoning and extending effective service cycle.

Integrated anti-carbon-powder-shedding sealed structure prevents secondary pipeline contamination

The carbon adsorption core is fully wrapped and fixed by stainless steel mesh and white drainage foam. Zero carbon powder shedding under long-term continuous compact airflow, preventing blockage and carbon contamination of micro spray nozzles, tiny laser optical lenses and miniature proportional solenoid valves.

Optimized low-loss flow channel design reduces power consumption of small air compressors

Smooth graded internal flow structure minimizes airflow resistance under rated full flow; dry-state pressure loss is far lower than generic aftermarket mini carbon filters, reducing continuous running load of mini screw compressors and portable air pumps, cutting long-term workshop electricity operating expenses.

Working Principle

Dry pre-purified compact-volume compressed air flows through the filter cartridge from outside to inside:

Front integrated microglass interception layer traps residual tiny liquid oil droplets and fine solid particles carried over from upstream PD45 ultrafine filter;

Clean dry gas penetrates the high-density activated carbon core; gaseous oil vapor, hydrocarbon and odor molecules are permanently adsorbed onto carbon micropores;

Outer stainless steel protective mesh prevents foam abrasion and carbon powder from flowing into downstream small-bore piping;

Oil-vapor-free, odorless ultra-clean compressed air exits from the inner stainless steel support tube and supplies terminal miniature precision production equipment.

Application Industries

Portable small electrostatic spray guns, mini laser marking equipment, laboratory analytical instrument air source, cosmetic micro-filling production lines, medical & dental small gas supply, miniature automation test benches, small food aseptic packaging equipment, precision electronic component assembly workstations requiring strict Class 0 oil-free compressed air.
