Pressure Regulator with Pressure Switch for Compressor Pressure Switch with 2 Displays Anyone who needs a pressure lower than indicated in the main line can rely on this pressure regulator. The pressure regulator can reduce the line pressure to the desired working pressure and keep it constant. Due to this characteristic, the pressure regulator is also called a pressure reducer. Pressure regulators are the ideal solution, especially when embedded parts have limited compressive strength. This pressure regulator convinces with its 20.67 mm external thread connection, 2 measurement displays or manometers, 2 compressed air quick couplings and a safety valve. So you have a complete compressed air unit with everything you need. The pressure regulator has a pressure display from 0 to 12 bar. The maximum operating voltage is 240 V / 16 A and the maximum allowable pressure is 8 bar.
