Coalescing Filters

Part No: 2901053600

Core Technical Specifications

Pre-filtration Interception Accuracy: Captures residual fine particles & liquid oil mist ≥0.01 μm

Filter Media Structure

Outer white hydrophobic PU anti-re-entrainment drainage foam

Front built-in multi-layer borosilicate microglass pre-screen to trap residual liquid oil droplets

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

Mounting Method: Central male thread bayonet quick twist lock, exclusive Atlas internal threaded locking structure

Standard Replacement Cycle

1,000 working hours / 12 months under clean low-oil-load industrial conditions; shorten to 600–800 hours in dusty, high-humidity spray workshops. Replace when air has obvious oily odor or differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of 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 integrated flow diversion ribs

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

Inner & Outer Support Cage: Double-layer perforated 304 stainless steel mesh, structural reinforcement to avoid carbon core deformation under full rated airflow

Key Product Advantages

Final-stage oil vapor removal barrier to produce ISO Class 0 100% oil-free compressed air

Glass fiber coalescing filters (DD/PD) can only remove liquid oil mist, while this QD-grade element adsorbs invisible gaseous oil vapor that penetrates coalescer media. It completely eliminates oily odor and organic volatile contaminants to protect high-precision production equipment and finished product quality.

High-capacity encapsulated carbon matrix with stable long service life

Uniform high-porosity coconut shell activated carbon filling provides massive adsorption storage capacity. Front microglass pre-layer blocks residual liquid oil mist before contacting carbon core, avoiding premature carbon poisoning and extending effective service cycle.

Integrated anti-carbon-shedding sealed structure, no secondary pipeline contamination

The carbon adsorption core is fully wrapped and fixed by multi-layer stainless steel mesh and white drainage foam. Zero carbon powder shedding under long-term continuous airflow, preventing micro spray nozzles, laser optical lenses and cleanroom pipelines from blockage and carbon pollution.

Atlas optimized low-loss flow channel design to reduce compressor energy consumption

Smooth graded internal flow structure minimizes airflow resistance; dry-state pressure loss is far lower than generic aftermarket carbon filters, reducing continuous load and power consumption of medium screw compressors, cutting long-term factory electricity expenses.

Working Principle

Dry, pre-polished 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 PD 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 piping;

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

Application Industries

Medium automotive electrostatic spray booths, medium heavy-duty laser cutting equipment, pharmaceutical mass aseptic filling production lines, central cleanroom air supply for electronics assembly, food & beverage sterile packaging factories, medical central medical gas supply, multi-station precision automation production lines requiring ISO 8573-1 Class 0 oil-free compressed air.
