1 General
1.1 Purpose
GHH RAND build and supply the compressor unit with motor SILU CG600
ready for operation. These units are used to handle bulk material
pneumatically owing to their ability to compress atmospheric air
free of oil. They can either be installed in a stationary unit or
mounted on silo-type trucks.

Important !!
The function of the non-return valve installed in the compressor
unit is to prevent the compressor, after having been switched off,
from running in reverse at high speed for a long time as a result
of residual pressure that exists in the discharge lines of the
pneumatic system.
To avoid an unintended return blow of material into the compres-
sor, it is mandatory that at least one further non-return valve is
installed in the pneumatic system of the silo arrangement.
