Product Line Details

ROOTS™ RAM™ Series Frames 404 thru 624 Unit is available in 8 different frames. All models feature “universal” mounting feet which allow the unit to be mounted in four different configurations. Piston ring seals reduce leakage through the shaft openings in the headplates. Lip type seals prevent lubrication from entering the air chamber.

Flow Range: 149 CFM to 3244 CFM
Pressure Range: 1 psi to 18 psi
Vacuum Range: 1″ to 16″Hgg (Dry)

RAM™ rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involute profile. 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 on all units.

Piston rings reduce air leakage through the shaft openings in the headplates, and lip-type oil seals prevent lubricant from entering the air chamber. A hydrodynamic seal on the drive shaft prevents shaft seal oil leaks.

RAM rotary blowers incorporate thrust control, with splash oil lubrication at both ends of the blower. All frame sizes are designed with detachable rugged steel mounting feet which permit in-field adaptability to either vertical or horizontal installation requirements.

Warranty: Twenty-four months of operation or thirty months from date of original purchase.
