PM-II Series VSD Two Stage Screw Air Compressor
One-shaft PM motor and air-end (air compressed element), avoiding transmission lost; with frequency converter, PM VSD air compressors save 42% energy than fixed-speed
PM-II Series
Description
PM-II Series VSD Two Stage Screw Air Compressor
Low noise and high-efficient with 2 stages compressing screw, no gear and with separated PM motor. Saving energy, reduce mechanical damages by 2 stage compression, to reach longer lifespan.
A cooling process conducts between two stages for reaching lower inlet air temperature and finally enlarge the free air delivery.
How does two stage screw air compressor work?
After the first stage of compression, compressed air is cooling down by the system between 2 stages, by lowering down its air temperature, so can reduce compression power.
Each motor for direct drive of compress element in preset ratio, which helps to reduce all.
