Filter regulator: Union tube diameter 1/4 inch, filter precision 40m, pressure range 0.05-0.85 MPa, adjustable pressure range 0.5-9.0 Kgf / cm2. Separator oil water: The water and oil separator should be connected to an air compressor to solve the problem of oil and water in the pipe. Suitable for different scenes, such as painting, electronic dust blowing, industrial automation equipment, medical equipment, etc. Air filter regulator and lubricating filter: The function of filter regulator to air is to regulate the pressure and to filter the oil and the humidity in the pipe; The function of the lubricator is to add pneumatic oil which enters the pipe through the air, which helps to lubricate and maintain the rear equipment. How to choose a filter regulator: If your equipment is solenoid valve or cylinder, you can choose this product. If your downhole equipment is paint sprayer or dust blower, choose product without lubricator. Recommend oil: Recommended to use ISO VG32 lubricating oil, it has good performance spray to lubricate system components.
