Tri-Lobe Rotary Air Blowers
RAM-X blowers have an exclusive Whispair discharge design that delivers, when combined with the tri-lobe impellers, air with reduced pulsation, less vibration, and quieter operation than conventional tri-lobe blowers. Reduced pulsation transmits less shock to the bearings, extending bearing life. All model sizes incorporate detachable steel mounting feet to adapt to horizontal or vertical configuration. Furthermore, a drive shaft extension allows top or bottom drive.
