Compressor with shaft coupling for direct drive mounted on a robust profile
base frame. Power transfer from motor to compressor takes place via an elastic
shaft coupling. This coupling is separable in the installed condition, which
thus enables maintenance work to be carried out on the compressor and motor
without having to dismantle them from the base frame. IEC standard motors of
type IMB3 may be used as drive motors.
Open type piston compressor for
external drive. The compressor design is very compact and robust. Dependable
mechanism lubrication is guaranteed by means of an oil pump which is independent
of rotating direction, as well as a large-volume oil sump.
