Show More Information || Hide More Information
Flow Range: 149 CFM to 3244 CFM
Pressure Range: 1 psi to 18 psi
Vacuum Range: 1” to 16”Hgg (Dry)
RAM™ WHISPAIR™ rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involute profile. Roots WHISPAIR blowers reduce noise and power loss by utilizing an exclusive wraparound plenum and proprietary WHISPAIR jet to control pressure equalization-feeding backflow in the direction of impeller movement, thereby
aiding rotation.
The headplates and rigid, one-piece casing are grey iron, while the drive end cover and gear cover are aluminum. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts, secured with a locknut. Cylindrical roller bearings are used.
Piston rings reduce air leakage through the shaft openings in the headplates, and lip-type oil seals prevent lubricant from entering the air chamber. RAM rotary blowers incorporate thrust control, with splash oil lubrication at both ends of the blower. A hydrodynamic seal on the drive shaft prevents shaft seal oil leaks.
All frame sizes are designed with detachable rugged steel mounting feet which permit in-field adaptability to either vertical or horizontal installation requirements. The top shaft is extended for drive on side outlet blowers, and either shaft can be extended for drive
on top or bottom outlet blowers.
Warranty: Twenty-four months of operation or thirty months from date of original purchase.
