【Filter Regulator】Union tube diameter 1/4 inch, filter accuracy 40μm, pressure range 0.05-0.85 MPa, adjustable pressure range 0.5-9.0 Kgf/cm². Filter regulator for compressed air 1/4 inch. Air pressure regulator 1/4 inch. Dair compressor filter. Moisture separator. Maintenance unit. 1/4" air tablet. 【Air Filter Regulator and Lubricator Filter】 The function of the air filter regulator is to regulate the pressure and filter the oil and moisture in the pipe; The function of the lubricator is to add pneumatic oil that enters the hose through the air, which allows lubrication and maintenance of the rear equipment. 【Water Oil Separator】The water and oil separator must 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. 【How to Choose a Regulator Filter】If your equipment is a solenoid valve or cylinder, you can choose this product. If your background equipment is a paint sprayer or a dust blower, choose a product without a lubricator.
