Key Product Advantages

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

GR1~GR4 coalescing filters only remove liquid oil mist, while this GR5 carbon element adsorbs invisible gaseous oil vapor that penetrates glass fiber 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 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.

Sullair 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 small & 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 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 lines, laboratory analytical instrument air source, cosmetic micro-filling production lines, medical & dental small gas supply, food aseptic packaging equipment, precision electronic component assembly workstations requiring strict oil-free air.
