Introduction
General description
The QOFT machines are two-stage rotary tooth compressors, driven by an electric motor. The
compressors deliver oil-free air. QOFT are air-cooled.
The compressors are enclosed in a sound-insulating bodywork.
The compressors are built up with following major components:
• Air filter (AF)
• Inlet silencer (IS)
• Load/no-load valve (UA)
• Low-pressure compressor element (El)
• Intercooler (Ci)
• High-pressure compressor element (Eh)
• Aftercooler (Ca)
• Electric motor (M1)
• Drive coupling
• Gear casing
• Q-Control Touch (1)
• Safety valves (SVh)
All compressors are so-called WorkPlace Air System compressors, which means they operate at
a very low noise level.
