Variable frequency drive (VFD) rotary screw compressors, also known as screw compressors, utilize a rotary screw as a positive displacement mechanism. VFD drive compressors adjust the motor speed so that the production of compressed air matches demand in real-time. With a dryer and filter, a total air system that delivers efficient performance. A rotary compressor is commonly used for tight installations and replacing a failed screw compressor or piston compressor in industrial applications.
