Description: This air compressor set includes three parts: air pressure reducing valve, filter and lubricator. Pressure reducing valve regulates air pressure and make the air in a constant state, to reduce hardware damagefrom abrupt change of air pressure. Filter cleans air and can filter themoisture in compressed air, avoiding water to enter device. Lubricator can lubricate moving parts and parts which are not convenient to add lubricant to greatly extend service life. Features: Made of high quality aluminum and plastic material, stronger than ordinary ones and more durable. Light weight and small design, easy installation, suitable for various installation.Regulates and reduce pressures of compressed air from 0Mpa to 1.0Mpa. Filter removes solid particles and condensate moisture in compressed air. Clockwise to increase pressure and anticlockwise to reduce pressure.
