Howden Roots Blowers Truck mounted blowers

Truck mounted blowers The Roots TRI-NADO™ TM Truck-Mount, Tri-Lobe Vacuum Blowers have been redesigned to incorporate the latest technology for reduced noise and vibration. 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 features include: • Cast-Foot Design for Reduced Vibration • Stronger Construction for Minimum Noise and Vibration • Progressive Chamber Design That Reduces Noise and Features Cooler Operation. 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.
