If damp gases are transferred with the pump, condensate may form
in the pump head during operation. This results in, among other
things, a reduction of the performance.
To ensure optimum suction capacity, it is possible to orient the
pump head downwards so that the condensate that forms can sim-
ply drain out of the pump head. For this purpose, the compressor
housing including pump head (depending on installation position)
can be rotated in increments of 90° and mounted.
