The pneumatic triplets are: set 1. Oil  water passing through the precision guide rod cylinder filter (filtering compressed air), 2. Pressure reducing valve (to adjust the pressure of the passing gas), 3. Oil mist device (for atomizing oil) The air source purification pneumatic component with integrated function.

The role  sequence of pneumatic triplets are:

1. The oil-water filter filters out water vapor, oil gas, dust impurities  the compressed air,  plays the role of air purification.

2. The pressure reducing valve regulates the pressure drop of the compressed gas passing through  stabilizes the working pressure).

3. The lubricator uses the flowing compressed air to extract  mix the lubricating oil in the lubricating cup  spray it into a mist-like gas into the pneumatic piping system to lubricate the pneumatic components, making the sliding parts of the pneumatic components smooth  durable .
