Feature
The 3/8" air filter and regular FRL combination unit 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 3/8" compressed 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 ).

Selection Tips
1.Buy the 3/8" air filter and regulator FRL combination unit from regular manufacturers. The market price of the compressed oil-water separators ranges from several hundred to several thousand. The quality difference is relatively large. There are also some fake and inferior products that may damage the injectors and even the engine. So when buying the oil-water separator you must go to a regular repair station to buy.
2.Choose a large displacement compressed oil-water filter. In order to ensure the fuel supply of the entire engine system, the additional oil-water separator model must be larger than the original car's own displacement.
The maximum working pressure of the 3/8" air filter and regulator FRL combination unit is 1.0 MPa, the pressure loss is small, and the water separation efficiency is high.
