Roots RAM Blower Series
Ductile iron rotary lobe blowers for heavy industrial duty.
Overview
The RAM series is built around a rugged ductile iron cylinder and headplates, with tapered roller bearings and helical timing gears. Sized from 404 through 624 for high pressure and vacuum service in wastewater, chemical and pneumatic conveying applications.
Key features
- Ductile iron cylinders and headplates for shock resistance
- Tapered roller bearings for heavier radial loads
- Helical involute timing gears run quieter than spur cut
- RAM-J jacketed variants available for temperature control
