5-476 HP | 18-2400 CFM Enclosed
5-476 HP | 18-2400 CFM Enclosed
Heavy-duty rotary screw compressors wrapped in sound-dampening enclosures.
CAS enclosed rotary screw models are built with the same heavy-duty components as our open frame models, but with a sound dampening enclosure. They combine the lowest dBA levels in the industry with highest levels of reliability, efficiency and productivity available. Our enclosures are built from solid, powder-coated steel, and feature access doors on all sides to make maintenance easier.
The CRD package is an upgrade to our enclosed rotary screw compressors, and includes the compressor, a receiver, a dryer, and other features.
