NOTICE! 
Risk of material damage from 
condensation! 
Cooling air with moisture content can 
cause condensation. 
-  Make sure that the cooling air is 
cool, dry and free of dust. 
1. 
Provide  the  required  rate  of  cooling  air  as  per 
the  technical  data  for  the  screw  compressor 
(
 Chapter 3 ‘Technical data’ on page 20). 
2. 
Extract the exhaust air as per the technical data 
for  the  screw  compressor  (
 Chapter 3 
‘Technical data’ on page 20). 
 
This  prevents  the  installation  room  and  the 
screw compressor from heating up. 
Forced ventilation and bleeding system 
(optional) 
The  forced  ventilation  and  bleeding 
equipment  must  be  dimensioned  so 
that  the  required  supply  and  exhaust 
air  can  be  supplied  and  extracted 
taking into account the existing residual 
thrust  from  the  cooling  air  fan.  The 
exhaust  air  can  also  be  used for  heat 
reclamation.

1. 
For  the  nominal  diameters  of  the  duct  connec-
tions  and  details  about  residual  thrust  refer  to 
the technical data (
 Chapter 3 ‘Technical data’ 
on  page 20)  and  the  installation  diagrams  in-
cluded in the scope of delivery. 
2. 
When connecting air ducts include the appropri-
ate  additional  supporting  fans  for  installation  in 
the ducts.
