ROOTS™ 412 RAM DVJ WHISPAIR Dry Vacuum Blower

Model: 412 RAM DVJ WHISPAIR

The ROOTS™ 412 RAM DVJ WHISPAIR dry vacuum blower delivers high capacity thermal management for industrial processes operating under extreme vacuum conditions. Producing a strong volumetric flow up to 1038 CFM, this system utilizes a cooling air jet system that feeds atmospheric air straight into the grey iron cylinder. This continuous cooling action completely isolates the housing from extreme heat distortion, enabling smooth, uncompromised performance without water injection or external cooling accessories.
