TRI-NADO®: TM Tri-Lobe Vacuum Pump

The ROOTS™ TRI-NADO® TM Truck-Mount, Tri-Lobe Vacuum Blowers have been redesigned to incorporate the latest technology for reduced noise and vibration. These heavy-duty rotary positive vacuum blowers are designed for continuous service in truck mounted operations.

More Information

Features

Casing-The casing is of one piece close-grained cast iron construction. The casing is heavily ribbed to prevent distortion under the most severe operating conditions and incorporates the ROOTS® Whispair™ feature for reduced pulsation, horsepower and noise levels
Impellers-The closed-end impellers are made from ductile iron with high tensile strength, and operate without liquid sealing or lubrication
Shafts-The shafts are 3" diameter alloy steel forgings flange connected to the impeller body
Timing Gears-The impellers are timed by a pair of alloy steel spur gears that operate in an oil bath. Bearings-The impeller/shaft assemblies are supported at each end by antifriction bearings
Lubrication-A patented jet spray oil slinger system provides lubrication to gears and bearings

Operating Principle

Incoming air is trapped by the pair of tri-lobe impellers. Simultaneously, pressurized air is being discharged (right). As the lower impeller passes the wrap-around flange, WHISPAIR™ jets equalize pressure between trapped air and the discharge area, aiding impeller movement and reducing power requirements. Impellers move air into the discharge area (right). Backflow is controlled, resulting in reduction of noise relative to conventional blowers.
