Motor

Replacement and upgrade motors for OPPAIR screw compressors, in three protection classes. IP23 is the open, ventilated design used on many standard frames; IP55 is the enclosed version for dusty or damp environments; IP65 with oil cooling is specified where the motor runs hot or the ambient is severe. Fitting the correct class matters, because an under-protected motor in a dusty plant fails early and an over-specified one adds cost without benefit. Motors are matched to the frame size, voltage and mounting of the machine they serve. Send us the compressor model, the serial number and the nameplate details and we will confirm the replacement.

For selection criteria, service points and site requirements, read our motor operating temperature and overheating causes.
