ROOTS TRI-RAM MODEL 728
TRI-RAM 728 is a replacement for the discontinued RAMX 770

Description:

Tri-RAM tri-lobe rotary blowers are heavy-duty units with high strength integral-shaft ductile iron impellers designed for maximum efficiency. The blowers feature Roots WHISPAIR discharge design which, when combined with tri-lobe impellers, delivers quieter operation than conventional tri-lobe blowers.

The headplates and rigid, one-piece cylinders are cast iron, and the drive-end and gear cover are aluminum (cast iron for models 722 - 832). Carburized and ground alloy steel spur timing gears are taper mounted on the shafts and are secured with a locknut (bolt for models 826 and 832). Cylindrical roller bearings are used to accept side loads from v-belt drives.

Piston rings reduce air leakage through the shaft openings in the headplates and hydrodynamic oil seals prevent lubricant from entering the air chamber. Tri-RAM blowers incorporate thrust control, with splash oil lubrication at both ends of the blower.
