CPVS Belt Drive Variable Speed Rotary Screw Air Compressors

CPVS 20 to 30 HP

The CPVS 20-30 HP variable speed compressors maintain a constant air pressure and will adjust the motor speed to meet your plant’s air demand. Variable speed drives are most efficient and reduce operating costs when operating between 40% and 85% capacity.

Chicago Pneumatic - Built In Protection

Built-in Protection

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. EMF (electromagnetic frequency protection) prevents electromagnetic frequency in the plant from damaging the VSD, as well as protecting plant equipment from magnetic frequencies that may be generated by the VSD.
