The Air Driven Classic Machine type FPL/R has a built-in air-motor and should be driven by compressed and oil mist lubricated air. The built-in air-motor may be damaged, if operated with non-lubricated air.
The Diprofil quick-coupling with on/off regulator type HSL-M and fog lubrication unit type MFB (or similar of other brands) should be used for connection to your compressed air system. NOTE! Protect the air inlet from dust and dirt, when not in operation.
