The 1/4" NPT air filter with delicate and compact structure, which is convenient for installation and application.
The pressed-in self-locking mechanism can prevent the abnormal movement of 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.
In addition to standard type, lower pressure type is optional ( The highest adjustable pressure is 0.4MPa ).

Tips
The working steps of the 1/4" oil-water separator in the car:
1. After the fuel enters the filter separator, the solid impurities are first filtered out by the filter layer.
2. In the demulsification layer, the oil and water in the emulsified state are separated.
3. In the 1/4" oil-water separator, small water droplets will condense into large water droplets and be stored in the sump.
4. Through the water repellent effect of the separated filter element, the small water droplets that do not condense are collected into the sedimentation tank, and then discharged from the drain valve.
5. Finally, drain the fuel whose moisture has been separated from the 1/4" NPT air filter with regular trap.
The 1/4” NPT air filter with regular trap is mainly to separate the water in the fuel, so that the fuel can be burned more fully in the engine cylinder, high performance oil-water separator with 15 cc drain bowl can make your engine work better.
