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:
Building on over 160 years of blower technology, our truck mounted blowers are quiet and powerful and are established as the ideal choice for vacuum truck OEMs.
2016 saw the launch of the ROOTS™ 827 DVJ WHISPAIR™, which has impressed with it's powerful and quiet performance. Find out more about 'The Beast'.
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.
The closed-end impellers are made from ductile iron with high tensile strength, and operate without liquid sealing or lubrication.
The shafts are 3” diameter alloy steel forgings flange connected to the impeller body.
The impellers are timed by a pair of alloy steel spur gears that operate in an oil bath.
The impeller/shaft assemblies are supported at each end by antifriction bearings.
A patented jet spray oil slinger system provides lubrication to gears and bearings.

The 827 dry vacuum-jetted (DVJ) blower available in gear-end drive for the vacuum truck market and opposite gear-end drive for the industrial market; where v-belt drive is typically preferred. This blower provides a complement to the Roots product family of vacuum truck blowers with performance similar to the Roots™ 1125 DVJ/ Tri-nado™, but a smaller footprint similar to the Roots™ 721 DVJ. Building on more than 165 years of Howden and Roots compressor technology, this blower will benefit vacuum truck OEMs and operators.
The 827 DVJ has 5,775 cfm free air available and is capable of achieving 27” Hg vacuum through the Roots® DVJ technology. “This will give our customers the added advantage of maintaining the free air and vacuum levels available in large blowers while providing this in a smaller package and thereby increasing the payload capacity of our customers trucks,” said Carlos Delgado, Howden Rotary Products Director.
The 412 HPT tri-lobe blower is an ideal option to improve operational performance with respect to unloading times, it can deliver 15% more flow than alternatives on the market. It is designed for continuous duties of 22 PSIG/18" HgVac, and intermittent duties of 25 PSIG/19" HgVac again putting it ahead of other similar class blowers available. The 412 HPT has an internal cooling fan which reduces the oil temperature by 30% against expected temperatures, this results in some key advantages; only one fill point is needed to lubricate both ends of the blower, expected oil lifespan is increased, and the maintenance of the blower is far easier.
Every product we deliver is backed by an unequivocal lifetime commitment to spare parts and product support.
