The air source treatment triple unit (pneumatic triple unit) includes three major components: air pressure reducing valve, filter, and oil mist eliminator. It is mainly used to purify and filter the air source entering the pneumatic instrument, and reduce the pressure to the rated air supply pressure of the instrument, equivalent to the function of a power transformer in the circuit.

1. The function of the pressure reducing valve in the triple unit of air source treatment is that the pressure reducing valve can stabilize the air source, keep the air source in a constant state, and reduce the damage to the valve or actuator hardware caused by sudden changes in air source pressure.

2. The function of the filter in the gas source treatment triple unit is to clean the gas source, filter the water in the compressed air, and prevent water from entering the device with the gas. 3. The function of the oil mist eliminator in the air source treatment triple unit is that the oil mist eliminator can lubricate the moving parts of the body and lubricate the parts that are inconvenient to add lubricating oil, greatly extending the service life of the body.
