CPVSd 35 to 50 hp

Variable Speed Drive Rotary Screw

The Chicago Pneumatic Variable Speed direct drive (CPVSd) compressor allows you to save operating costs when your application does not require the compressor’s full capacity. Artificial intelligence automatically maintains designated pressure and provides only the air that your system requires. As a result, you save energy and money. The CPVSd is great as a stand-alone machine or networked to a base-load compressor where it can function as a trim machine.
