Key Product Advantages

Core high-precision polishing stage to drastically extend downstream carbon filter service life

Installed after MKO-2700-X medium coalescer, Y grade captures invisible trace submicron oil mist and micro water droplets that 1μm medium filters cannot separate. It drastically reduces liquid contamination load on terminal MKO-2700-A activated carbon elements, extends carbon service cycle by over 60% and cuts factory spare parts procurement cost.

Large dust & oil holding capacity with stable low differential pressure for continuous industrial production

Proprietary deep-fold microglass matrix stores large volume of oil sludge, pipeline rust and solid dust without rapid pressure rise, perfectly matching 24/7 non-stop production for medium-flow manufacturing workshops. Outer hydrophobic foam rapidly drains separated liquid to filter bowl drain port and minimizes oil re-entrainment risk.

High-temperature stable glass fiber media eliminates fiber shedding and full-system pipeline contamination

High-temperature fully cured borosilicate microglass maintains complete structural integrity under sustained 80°C operating temperature without softening, pulverization or fiber shedding. Zero glass fiber debris enters industrial piping to block spray guns, industrial laser optical lenses and proportional process control solenoid valves.

Low permanent differential pressure energy-saving design to reduce air compressor power consumption

Uniform gradient pleat layout delivers minimal airflow resistance over full service cycle under full rated flow capacity. Stable low backpressure reduces continuous motor loading of medium screw air compressors and significantly lowers long-term factory electricity operating costs.

Working Principle

Medium-volume pre-dried compressed air flows through the filter cartridge from outside to inside central core:

Large water droplets and coarse solid impurities are trapped by outer hydrophobic foam and drain down to the filter bowl drain port by gravity.

0.01μm oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient borosilicate microglass media.

Outer integrated anti-re-entrainment foam barrier prevents separated liquid oil and water from being re-carried by high-speed medium-volume industrial compressed airflow.

Collected oil and condensate are automatically discharged via industrial electronic zero-loss drain valve.

Ultra-clean air with residual liquid oil ≤0.008 mg/m³ flows downstream to MKO-2700-A activated carbon filter for secondary gaseous oil vapor & odor removal purification.

Application Industries

Medium automotive component electrostatic spray booths, medium-format industrial laser cutting & welding workshops, medium-scale pharmaceutical central aseptic filling air supply stations, cosmetic batch filling production lines, laboratory & medical high-purity gas supply, food & beverage medium sterile packaging equipment, medium-sized electronics assembly cleanrooms requiring strict ISO 8573-1 Class 1 ultra-clean compressed air.
