1. Compressed air maintenance unit pressure reducer: The compressed air regulator is an efficient maintenance unit with filter and water separator for use on compressors. The 1/4 inch compressed air pressure regulator water separator with pressure gauge and 1/4 inch compressed air maintenance unit extends the life of your compressed air tools by protecting them from dirt particles, water, and chemical impurities. 2. Compressed air regulator for compressor filter: The oil water separator provides precise control and delivers clean, dry air. It features a small size, lightweight design, and easy installation and maintenance. With the adjustable pressure regulator and pressure regulator compressed air water separator, you can adjust the desired pressure by pulling the black button at the of the regulator up and turning it. 3. Compressed air with pressure gauge maintenance unit: The 1/4 inch compressed air water separator oil filter reduces or maintains air pressure. The compressed air maintenance unit pressure regulator (1/4 inch) keeps the working pressure constant, and the air pressure holding device performs vacuum compression by adding air to effectively remove dirt and condensate, then mixes with adjustable oil. 4. Pressure range and temperature range: The water separator for compressors has a pressure adjustment range of 0.5 to 8.5 kg/cm, with a maximum adjustable pressure of 9.5 kg/cm. The operating temperature range is 5 to 60°C. The pneumatic pressure regulator with pressure gauge is an efficient maintenance unit with filter and water separator for use on compressors.
