VS Series direct-drive variable speed screw compressors
Gardner Denver
Direct-drive variable-speed (VSD) screw compressors from 7.5 to 290 kW. The inverter matches motor speed to actual air demand, cutting energy consumption by up to 30 %. Larger models (160–290 kW) use FOURCORE two-stage airend technology for 8–12 % higher efficiency than single-stage machines.
