2. Worldwide Excellence in Air Technology –
Dedicated to the Success of Your Pneumatic Applications
Air Motors/Gearmotors
Known industry wide for their rugged construction and reliability, Gast Air
Motors and air powered Gearmotors are used in a variety of applications.
Lubricated Air Motors come in seven basic models up to 9.5 HP (7,1 kW);
motor speeds are variable from 300 to 10,000 RPM. Oilless versions, which
require absolutely no lubrication, come in three basic models ranging from
.18 to 2.5 HP (0,13 to 1,86 kW) and with motor speeds up to 4,000 RPM.
Choose from hub, foot, face, NEMA C-Flange or Metric D Series interface
mountings and clockwise, counterclockwise or reversible rotations. Four
and eight vane models are also available.
Air powered Gearmotors are available in rightangle and in-line models
offering a maximum torque range of 73 to 5,200 lb. in. (8 to 587 Nm) and
gear ratios from 10:1 to 60:1 single reduction gear reducers. A full line of
recommended accessories is also available.
• Minimum maintenance.
You can put a Gast Air Motor in places where
they will not get much service, because there’s
virtually nothing to service on a Gast Air Motor,
providing it is operated on a clean, dry, and lubri-
cated air supply*.
• Will not burn out.
Gast Air Motors can be stalled or overloaded for
long periods without damage.
• Low price.
Cost is less than other motors of equal horse-
power and capabilities.
• Operate in all positions.
Mount them sideways, upside-down, or in
any position so long as adequate lubrication*
is provided and end thrust is kept to design
limits. Gearmotors will operate in almost any
position, see model data.
• Low-shock starts.
Because Gast Air Motors go to work
with air-cushioned smoothness, they
cut stress on your equipment.
• Self-sealing vanes.
Vanes are self-sealing and automatically take up
their own wear, thus ensuring con­stant output
for thousands of hours of use.
• Mounting flexibility.
Foot, hub, face, NEMA-C or metric flange
motor mountings are standard equipment for
most air motor sizes.
• Four-vane or eight-vane.
Four-vane units meet most requirements,
but for more precise inching control and
minimum blowby in applications where mo-
tor is operating in a stalled condition, specify
eight-vane models.
• Long-life accessories.
To ensure long life, Gast offers accessories
designed to extend unit life including air fil-
ters that remove water and particles down
to 5 microns, and air line lubricators that
supply a constant flow of lubrication auto-
matically*. We can supply a pressure regula-
tor that provides precise control of power
and operating speed. Options like these help
you get smooth performance with minimum
maintenance.
*Non-lubricated series does not require a
lubricator
• Variable speed.
You can vary air motor speed between 300
and 10,000 rpm (depending on model
selection) with a simple valve put in
between the air source and air motor.
• Nonelectrical sparking.
As a nonelectrical device, the possibility of
explosion from igniting flammable gases is
greatly reduced.
• Instantly reversible.
A four-way valve in the air line enables
a Gast Air Motor to be instantly reversed. A
turn of the valve causes a complete
reversal of rotation, even when the motor is
running at full speed.
• Cool running.
As the air motor turns, expanded air cools
the motor. Units can be used in ambient
temperatures up to 250°F (120°C) in an non-
hazardous atmosphere.
• Compact and portable.
Get maximum horsepower with minimum
size and weight.

How to select an air motor.
Air motors differ in many ways from other power sources.
These unique operating characteristics must
be considered when selecting an air mo-
tor for a particular job. It is easy to change
horsepower and speed of an air motor by
throttling the air inlet. Therefore, the best
rule of thumb for selecting an air motor is to
choose one that will provide the horsepower
and torque needed using only two-thirds (2
/3
)
of the line pressure available. The full air line
pressure will then be available for overloads and start-
ing.
• Output Power vs Speed.
The output power of an air motor is relative to speed and
to air line pressure.
• Torque vs Speed.
1. An air motor slows down when load increases…
at the same time its torque increases to a point where
it matches the load. It will continue to provide increased
torque all the way to the stalled condition, and it can
maintain the stalled condition without any harm to the motor.
2. As the load is reduced, an air motor will increase speed
and the torque will decrease to match the reduced load.
3. When the load on an air motor is either increased or
decreased, speed can be controlled by increasing or
decreasing air pressure.
4. Starting torque of an air motor is lower than running
torque. While this provides smooth, low-shock starting,
it is necessary to have additional air line pressure for
starting under heavy loads.
• Air Consumption vs Speed.
Air consumption increases as speed and air pressure is in-
creased.
Use of Air Motors in Hazardous Atmospheres
Most of the Gast air motors and some of the gearmotors in this
catalog meet the requirements of the EC directive 94/9EC (ATEX
100a). They may be used in zones 1 and 2 where explosive at‑
mospheres of gas or dust are likely to occur. These are marked
with II 2 G D c T4 in the catalogue and on the product. This
indicates the air motor is Group II, Category 2, Gas and Dust
Atmospheres, and a maximum surface temperature of 275O
F/
135O
C Check that the product driven by the air motor meets
ATEX directive.
There are several points regarding the safety of air motors. Our
air motors are not a source of electric sparks. However, it is
possible that an article which is not part of the air motor (e.g.,
wrenches, hammers, etc.) could create a spark by sharply im‑
pacting a cast iron or aluminum case or the steel shaft of the air
motor. [Note that electric motor enclosures for both class 1 and
II hazardous locations can be made of “...iron, steel, copper,
bronze, or aluminum...” (UL 674, Electric Motors and Generators
‑ Hazardous Locations, June 23, 1989; paragraph 4.2, page 6)].
Gast air motors are designed to be operated by compressed air, the
expansion of which creates a cooling effect. As a result, the outside
surface temperature of the air motor will not reach ignition tempera‑
ture. A maximum surface temperature of 275O
F/135O
C Operation of
the air motor with compressed air purges a flammable mixture from
the inside of the air motor. To prevent static electricity from be-
ing an ignition source electrically ground the metal air motor.
We do not guarantee the safety of any application, but to ensure the
safe operation of an air motor in your application, always follow the
product operation manual, follow ATEX 100a when operating in
a hazardous atmosphere and consult with a qualified engineer.

15. Non-lubricated Air Motors
The NL Series - an alternative to
our traditional lubricated styles
because no lubricator is necessary
Gast's non-lubricated Air Motors
provide the advantages and
benefits of traditional lubricated Air
Motors which include:
• Variable speed
• Nonelectrical sparking
• Cool running
• Minimal maintenance
• No-shock starts
• Any plane operation
For those air motor
applications where
contaminated exhaust
cannot be tolerated in the
workplace, Gast's
non-lubricated air motors,
the NL series, provide the
solution.
• Rugged and reliable
Like our traditional lubricated air motors, the NL
series will provide thousands of hours of service-
free life. Vanes are just as easy and inexpensive
to replace.
• Performance flexibility
Gast's non-lubricated air motors are designed so
that compressor carry-over will not gum up the
vanes. In fact, while no lubrication whatsoever
is required to operate the motors, small amounts
of oil and water will actually improve the
performance.
• Corrosion resistant
Because the body, rotor and end plates are
specially treated, these air motors can tolerate
unfavorable moisture-laden conditions.
• No oil expenses
If you are using several quarts of oil throughout
the year, you'll eliminate that expense with
non-lubricated air motors.
• No periodic inspection
With no in-line lubrication system to replenish,
the need for time consuming maintenance
checks is eliminated.

20. Air-Powered Gearmotors
More reasons why you should
switch from electricity to air.
If you compare Gast Air-Powered Gearmotors with
any electric-powered gearmotor, there’s really no
comparison. Here’s why:
• More horsepower.
Size for size, weight for weight, you can’t beat a Gast
Gearmotor. A typical rotary vane air motor – the type
used in gearmotors – developing 21
/2
hp (1,9 kW) at
1800 rpm and 90 psi (6,2 bar), weighs just 17 pounds
(7,7 kg). A comparable electric motor may be two or
three times heavier.
• More speed control.
You can’t get more precise turning power than with
a Gast Gearmotor. In applications where you need
variable speed – like bolt tensioning equipment or rock
drilling rigs – one-speed electric motors just won’t fit
the bill. Precise lifting, lowering, or turning is simple with
Gast Gearmotors.
• More flexibility.
More than most standard electric-powered gear reduc-
ers can provide. Gast Gearmotors give you infinitely
variable turning power from 73 to 5200 lb. in. (8 to
587 Nm) of torque. And Gast Gearmotors are instantly
reversible through easy valving in the air line.
• More configurations.
That makes it easier for our product to work in your
product. Our gearmotors are available in four mounting
configurations.
• More life.
Unlike electric-powered gearmotors, there’s no chance
of burnout with a Gast Gearmotor. They can be stalled
indefinitely with no heat buildup. They’re nonelectri-
cal sparking, too, which makes them ideal for use in
potentially explosive environments – places where you
couldn’t even consider electricity.
bWARNING: Gast Air Powered Gearmotors are not
self-locking. In applications where a break is required
for safety in case of air pressure failure, call
800/952-4278 for your nearest distributor.
Get the right gearmotor
with all the right options.
Pictured: typical rightangle, worm gear reducer.
A. Bearings
Ball bearings used on input shaft; tapered roller bearings
used on output shaft.
B. Case
Fine close-grain cast iron; crankcase sealed; duplex-
milled for parallelism of mounting surfaces.
C. Worm
8620 alloy steel thread rolled to give uninterrupted grain
pattern; carburized and hardened after rolling; high-
burnish contact surface from rolling reduces friction
coefficient for less heat generation, lower power losses.
In large sizes, worms are cut, hardened, and ground to a
good micro-finish, providing the ultimate in efficiency and
torque capacity.
D. Worm Gear
Forged bronze; geometry and high helix angle give
maximum beam strength, high efficiency.
E. Cap Screw
High-strength fasteners with corresponding torque
specifications
prevent loosening or breaking.
F. Seals
Double-dipped and spring-loaded for leak proofing;
tested to ensure compatibility with lubricant.

Filters Regulators Lubricators
An air pressure regulator is
necessary in most air motor
applications to maintain a
constant pressure regardless of
the rise and fall of line pressure.
A filter helps ensure efficient
operation by removing solid
and liquid contaminants
before they enter the air
motor.
