    Pneumatic& Coolant Systems 8.3 Pneumatic System The compressed air passing through the F.R.L. (air filter, air regulator, and air lubricator) combination is used to clean the tool holder and spindle taper hole. The compressed air pressure is regulated under 5 bar. The air pipe lines and solenoid valves are also lubricated by these mixture of oil and air.
