Key Product Advantages

lt drastically reduces oil contamination load on terminal activated carbon cartridges, extends carbon service life and cuts overall system maintenance cost. Silicon-free formulation is optional for automotive topcoat painting lines to eliminate paint pinhole defects.

High liquid holding capacity for high-humidity workshop environments

Thick deep-pleated gradient micro glass fiber matrix stores large volumes of condensed oil and water, resisting rapid saturation in facilities with underperforming aftercoolers or refrigerated dryers. It is widely installed upstream of adsorption dryers to protect molecular sieve from permanent oil fouling.

Low airflow resistance to lower long-term compressor energy consumption

Optimized deep-fold micro glass fiber maximizes effective filtration area, maintaining stable low pressure drop under 24/7 continuous full-load operation, minimizing extra power draw of air compressor units.

Hydrolysis & abrasion resistant media with zero fiber shedding

Oleophobic borosilicate micro glass fiber combined with stainless steel support cage prevents fiber detachment under long-term humid compressed air impact, avoiding secondary pipeline contamination to downstream precision processing equipment.

Working Principle

Pre-cleaned compressed air from X medium coalescer flows outside-in through the filter cartridge:

Residual bulk condensed water and fine solid particles are blocked by outer white hydrophobic foam layer;

Trace micro oil & water aerosols collide and coalesce into large liquid droplets through multi-layer gradient borosilicate micro glass fiber media;

Outer anti-re-entrainment foam prevents coalesced liquid droplets from being re-entrained into high-speed airflow;

Separated oil and condensate drain down to the filter bowl by gravity and automatic drain valve;

Ultra-dry, trace-low-residual-oil compressed air flows downstream to activated carbon filter for complete oil vapor adsorption treatment.

Application Industries

Automotive electrostatic spray booths, small laser cutting machines, pharmaceutical sterile filling lines, food aseptic packaging, PCB laboratory manufacturing, precision analytical instruments, medical breathing air pretreatment, small factory standalone air compressor stations, solvent coating production lines, high-precision miniature pneumatic automation equipment, front protection filter for small adsorption dryers.
