Core Technical Specifications

Outer white hydrophobic PU anti-re-entrainment drainage foam

Front multi-layer borosilicate microglass pre-screen to block residual liquid oil droplets

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

Flow & Dimension Parameters

Overall Size: Height 136 mm, Outer Diameter 42 mm

Mounting Method: Central bayonet plug-in quick twist lock, exclusive Sullair internal positioning mandrel

Operating Limits

Max Working Pressure: 1.6 MPa (16 bar)

Continuous Operating Temperature: 1.5℃ ~ 60℃

Inlet Air Prerequisite: Air must pass through refrigerated/desiccant dryer + GR4 ultrafine coalescer; no 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 workshops. Replace 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 plug-in locking head with integrated flow diversion ribs

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

Inner & Outer Support Cage: Single-layer perforated 304 stainless steel mesh, lightweight rigid support to prevent carbon core deformation under rated airflow

Key Product Advantages

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

GR1~GR4 coalescing elements only separate liquid oil mist, while this GR5 carbon cartridge adsorbs invisible gaseous oil vapor that penetrates glass fiber media. It completely removes 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 delivers massive adsorption storage capacity. 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-shedding sealed structure, no 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 airflow, preventing blockage and carbon contamination of micro spray nozzles, laser optical lenses and cleanroom pipelines.

Sullair optimized low-loss flow channel design to cut 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 small & medium screw compressors, lowering 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 GR4 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

Small & medium automotive electrostatic spray booths, mini laser marking & cutting equipment, pharmaceutical small aseptic filling production lines, laboratory analytical instrument air source, cosmetic micro-filling lines, medical & dental small gas supply, food aseptic packaging equipment, precision electronic component assembly workstations requiring strict oil-free air.
