Feature
The 1/2" 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 1/2" 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 ).

Tips
The device must be installed correctly, and qualified operators must be commissioned and maintained in accordance with the operating instructions to make it operate safely.
Failure to close the isolation valve during installation and maintenance will cause damage to the components of the system and cause harm to the human body. The danger also includes: the protection device and the ventilation pipe or the alarm system are closed. Ensure that the isolation valve is closed to avoid the impact of the system.
Pressure: When maintaining and repairing, consider whether there is a medium in the oil-water separator pipeline. Make sure that the pressure medium has been isolated and the safety airway has been open to the atmosphere. This can be solved by installing a drain valve, even if the pressure gauge indicates zero. Don't think that the system is drained.
Temperature: After closing the isolation valve, there should be a period of time to make the operating part close to normal temperature to avoid burns.
Disposal: The product can be recycled. Properly handled will not cause ecological problems.
The 1/2" compressed air filter and regular FRL combination unit with 90CC big bowl is easy to operate and has stable performance and strong anti-interference ability.
