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.

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-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.
■
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 troublefree performance and durability.
3
■
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 gurations 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 providing 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, distribution piping. Every pressure lubrication option
includes, gearbox oil sump, oil fi lter 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.

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.
