• Swept volume tor type GSL 480 is based on 1450 rpm, which is the practical max. speed tor this type.
·• This minimum value is valid only for compressor packages with oil injection into the rotor grooves by pressure ditterence.
Mind! The figures, mentioned in the table above apply on'ly to the compressor GSL itself. The operation limitations retated to
the packages should take precedence of the design limitations of the compressor. For settings of pressure and tempe
ratures safoty devices
