Product Description

7bar-13bar Industrial Electric Silent 22kw 30HP Heavy Duty Screw Air Compressor DHH DM series variable frequency (VSD) screw compressors are a new rotor profile design that combines a permanent magnet motor and a variable speed frequency converter. Coupled with the high-quality main engine, it shows the advanced screw compressor technology.
Compared with fixed speed air compressors, VSDs cost less for the same air demand. Therefore, the VSD air compressor can save a lot of cost and electricity bills compared with the fixed speed type. Technical Parameters
