Product Specifications
The Roots Ram blower WHISPAIR™ series is designed for high efficiency and reduced noise in demanding industrial environments. RAM-J units feature the original WHISPAIR jets, which control pressure equalization by feeding backflow in the direction of impeller movement. This design reduces noise and power loss while aiding rotation. The WHISPAIR feature results in uni-directional flow and drive shaft rotation.
