    The structure of the 1/8" NPT air filter is delicate and compact, which is convenient for installation and application.
    preventing the abnormal movementof the set pressure caused by external interfere.
    The pressure loss is low and the efficiency of The 1/4"oil-water separator is high.
    The quantity of oil dripping can be directly observed through transparent checkdome.
    Lower pressure type is optional (The highest adjustable pressure is 0.4MPa).

    air filter with regular trap


    The working principle of the 1/8" NPT air filter with regular trap :

    1. The oily sewage is sent to the oil-water separator by the sewage pump, after passing through the diffusion nozzle, the large oil droplets will float on the top of the left oil collection chamber.

    2. The sewage containing small oil droplets enters the corrugated plate coalescer in the lower part, where the polymerized oil droplets form larger oil droplets to the right oil collecting chamber.

    3. Sewage containing oil droplets with smaller particles passes through a fine filter to remove impurities in the water and enter the fiber polymerizer in turn, so that the fine oil droplets are aggregated into larger oil droplets and separated from the water.

    4. After separation, the clean water is drained through the drain port, the dirty oil in the left and right oil collection chambers is automatically drained through the solenoid valve, and the dirty oil separated in the fiber polymerizer is drained through the manual valve.

    Air filter met expectations
    I purchased this 0.9 Mpa type of air pressure regulator to replace one that was leaking air on my old air compressor. Quality seems to be great and operates as expected. Having used for a months and all went well.
