Page 1 

PREFACE 

 
Sperre has produced this instruction manual in order to provide users of its compressor equipment 
with information about the compressor’s construction and operation, as well as basic information about 
inspection and maintenance. 
 
It is important that the operator should familiarise himself with the contents of this instruction manual, 
so as to ensure that installation, use and maintenance work is carried out in a correct and safe manner 
from the outset. 
 
The maintenance intervals and individual technical data are average values based on experience, and 
may vary, depending on the compressor’s operational parameters. 
 
The supplier accepts no responsibility for damage resulting from careless operation or inadequate 
maintenance. Keep the compressor in good mechanical condition, and remember that preventive 
maintenance of the equipment reduces the danger of damage and unnecessary operational 
interruptions. 
 
Sperre reserves the right to modify details without prior warning.
