GE Roots RAS-J (Air) / RGS-J (Gas) blowers

These blowers are industrial and high vacuum air and gas service providers delivering single and multiple stage arrangements. They are widely used in various industries, including wastewater treatment, pneumatic conveying, steel degassing, and vacuum trucks. Here are some key features and use cases of these blowers:

Wide range of performance for pressure and vacuum applications on air or gas service for both dry and wet (liquid injection) conditions.
Available in size ranges that can be economically direct driven by an electric motor.
Extensive application engineering, global service support, and packaging capability.

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.

WHISPAIR Technology Features

■

Lower energy consumption. The patented

WHISPAIR jet design precisely meters back-ﬂ ow

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.

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.

■

Cylinder and headplates. All RAS-J and

RGS-J blower units are conﬁ gurable to

horizontal or vertical ﬂ ows. 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 trouble-

free performance and durability.

■

Shafts. Impeller shafts are alloy steel forgings;

ﬂ ange 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 conﬁ g-

urations to meet customer speciﬁ c 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 ﬁ t. Larger

sizes use a proven taper locking device provid-

ing an easily adjustable mechanical shrink ﬁ t.

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, distribu-

tion piping. Every pressure lubrication option

includes, gearbox oil sump, oil ﬁ lter oil cooler,

pressure gauge, relief valve and low oil pres-

sure 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.

Note 1: Standard drive shaft location is dependent upon frame size:

10xx through 14xx frame sizes - drive shaft is located on the opposite gear end of the machine and is shown in heavy type.

16xx through 20xx frame size - drive shaft is located on the gear end of the machine as shown by dotted lines.

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 speciﬁ ed.

Frame sizes 10xx through 14xx can be belt driven with the addition of an optional extra bearing and selection of correct pulley combination.
