GE Energy Roots * RAS-J Air & RGS-J Gas Blowers Wide range of performance for pressure and vacuum applications on air or gas service for both dry and wet (liquid injection) conditions.
GE Energy s Roots blower models deliver industrial and high vacuum air and gas services including single and multiple stage arrangements. Roots rotary blowers have been applied to multiple applications in a very wide range of industries aeration for wastewater treatment, pneumatic conveying for both vacuum and pressure conditions, steel degassing, vacuum truck, and many others. These blowers are available in size ranges that can be economically direct driven by an electric motor. They are available with extensive application engineering, global service support, and packaging capability. 2
The GE proprietary WHISPAIR * design reduces stress, vibration and noise in your blower and piping system. Conventional blowers produce downstream pressure pulse waves which buffet your air or gas delivery system up to 120 times per second. These pulses and vibrations can steal power and shorten the life of every bearing, gear and other drive train component. WHISPAIR technology reduces the strength of the blower pulse up to 40%, throughout the air/gas delivery system. WHISPAIR Technology Features Lower energy consumption. The patented WHISPAIR jet design precisely meters back-flow and channels air pressure in the direction of impeller rotation. The result is an extra push that reduces the power required to drive the impellers. Longer bearing life. Less pulse transmitted through the impellers means approximately 20% longer bearing life. With less pulse and vibration, other components such as timing gears, drive couplings, v-belts and motor bearings suffer less stress. Less noise. Pressure pulses are often the major source of blower and gas blower noise. The pressure equalizing effect of the WHISPAIR design reduces noise by approximately 5 dba, while reducing wear on your piping valves and sensitive instrumentation. Cylinder and headplates. All RAS-J and RGS-J blower units are configurable to horizontal or vertical flows. Cylinders and headplates are precision machined grey iron, with cast ribs for improved strength and heat transfer. Castings may be subjected to strenuous pressure and leak testing to help preserve integrity in the most demanding applications. Each RGS-J machine is leaked tested to 1.25 times casing design pressure; optional hydrostatic testing available to 1.5 times casing design pressure. Impellers. Made from ductile iron with a tensile strength of 60,000 psi impellers are statically and dynamically balanced to industry accepted standards, providing you with years of troublefree performance and durability.

Shafts. Impeller shafts are alloy steel forgings; flange connected to the impeller bodies with high-tensile socket head capscrews. Standard blowers have precision machined labyrinth seals where the shaft passes the casing headplate. A single piston ring or multiple piston rings may also be employed with various purge gas configurations to meet customer specific requirements. Bearings. Long-life, double - row spherical roller bearings support the shaft assemblies and control axial location of the impellers at the thrust end. An inboard 5th bearing helps reduce drive shaft stress on 1000J through 1400J frame size, V-belt driven blowers. Timing gears. The impellers rotation is timed by a pair of precision machined, forged steel gears. These wide-faced spur gears are manufactured to AGMA standards and are carburized and ground with a hardness of 58-60 Rc. Spur gears do not transmit harmful axial loads to bearings and motors. On 1000J frame size units the gears are secured to the shafts by a taper fit. Larger sizes use a proven taper locking device providing an easily adjustable mechanical shrink fit. No shaft-weakening keyways or locking pins are required. Lubrication Both RAS-J blowers and RGS-J blowers offer a positive pressure lubrication system which can extend bearing life by up to 50%. This system is entirely self-contained and includes an integral drive oil pump, distribution piping. Every pressure lubrication option includes, gearbox oil sump, oil filter oil cooler, pressure gauge, relief valve and low oil pressure safety switch. This is a pressure lubrication system that supplies cool, clean pressurized oil into every critical area. The Roots RAS-J blower is also available with an energy-saving splash lubrication system in place of the pressure system.

For all direct drive applications torsional analysis of the whole drive train is required and in the case of drivers other than electric motors, gear end drive must be specified. Frame sizes 10xx through 14xx can be belt driven with the addition of an optional extra bearing and selection of correct pulley combination. 9
