The Chicago Pneumatic Variable Speed (CPVS) 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 CPVS is great as a stand-alone machine or networked to a base-load CP compressor where it
can function as a trim machine.
DESIGNED TO LAST
Every CPVS comes with a rugged, Vacon variable speed drive that does much more than simply control the speed of the
motor. The VSD comes completely programmed and wired, so time spent on installation and set-up are minimized. The
VSD also includes, as standard, a removable LCD display, integrated cooling fans, built-in line reactor and electromagnetic
SETTING THE STANDARD
Competitive VSD compressors require external vents to keep the VSD cool during operation. These VSDs still overheat
and ultimately fail in the field because they become contaminated, as dust and debris are ingested over time. The VSD
on the CPVS has integrated fans which use cool air from the intake and do not require vents in the door to the electrical
cabinet. So the VSD always stays cool and protected!
The line reactor protects against voltage spikes and
fluctuations, also known as “dirty voltage”. A common
example occurs when generators are used to run the
compressors. Voltage fluctuations from the generator
cannot be adequately controlled, which will result in
damage to the compressor motor and VSD.
