Pneumatic coupling refers to air filter and pressure reducing valve. The pressure reducing valve can stabilize the pressure of the gas source, so that the gas source is in a constant state, which can reduce the damage to the valve or actuator and other hardware when the air pressure of the gas source changes abruptly. The filter is used to clean the air source. It can filter the water in the compressed air and avoid the water entering the device with the gas.
