The Gast
Group
Difference
Products for Almost Any Application – Worldwide
We offer an extensive and versatile line of air-moving products, including vacuum pumps, compressors, air motors,
gear motors, vacuum generators, and regenerative blowers. We design and build these components for original
equipment manufacturers worldwide, but we also develop complete pneumatic solutions to solve tough customer

Why use a Gast Air Motor?
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. Gear Motors 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 motor 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 filters that remove water and particles down
to 5 microns, and air line lubricators that supply a constant flow of
lubrication automatically*. We can supply a pressure regulator 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.
Non-electrical Sparking
As a non-electrical 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 a
non-hazardous atmosphere.
Compact and Portable
Get maximum horsepower with minimum size and weight.
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 lubricated 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 horsepower and capabilities.
Air motors differ in many ways from
other power sources. These unique
operating characteristics must be
considered when selecting an air
motor 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 starting.
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
increased.
How to Select
an Air Motor

Air Motor/Gear Motor Performance Overview
The units that we list in this catalog are a small portion of what we actually make. Those listed are considered “standard
units” and are normally available from stock in small quantities. Variations are produced for many customers and by
providing to us the application specifications we might find an existing unit that fits your requirement. If we don’t and the
quantity is sufficient, we will design a “special unit” for the application.
Pictorial and dimensional data is subject to change without notice.
The information presented in this catalog is based on technical data and test results of nominal units. It is believed to be
accurate and is offered as an aid in the selection of Gast products. It is the user’s responsibility to determine suitability of
the product for intended use and the user assumes all risk and liability whatsoever in connection therewith.
The specifications listed are that of a unit at sea level with an ambient temperature of
70 °F (21 °C), operating with normal electrical current conditions. The figures stated in
this catalog are nominal approximations for models without accessories. Intake filters and
exhaust mufflers, and the accumulation of contaminants in them during operation, will
decrease the flow of air as well as the achievable pressure.

Use of Air Motors in Hazardous Atmospheres
�
�
�
Most of the Gast Air Motors and some of the Gast Gear Motors
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 atmospheres 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
275 °F/135 °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
impacting a cast iron or aluminum case or the steel shaft of the
air motor. [Note that electric motor enclosures for both class I
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 temperature and a maximum surface temperature of
275 °F/135 °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 being 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.

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
• Non-electrical sparking
• Cool running
• Minimal maintenance
• No-shock starts
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 com-
pressor 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 per-
formance.
• 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.

Air-Powered Gear Motors
More reasons why you should
switch from electricity to air.
If you compare Gast Air-Powered Gear Motors with any
electric-powered gear motor, there’s really no comparison.
Here’s why:
• More Horsepower
Size for size, weight for weight, you can’t beat a Gast Gear
Motor. A typical rotary vane air motor – the type used in gear
motors – 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
Gear Motor. 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 Gear Motors.
• More Flexibility
More than most standard electric-powered gear reducers can
provide. Gast Gear Motors give you infinitely variable turning
power from 73 to 5200 lb. in. (8 to 587 Nm) of torque. And Gast
Gear Motors 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 Gear Motors are available in four mounting configurations.
• More Life
Unlike electric-powered gear motors, there’s no chance of
burnout with a Gast Gear Motor. They can be stalled indefinitely
with no heat buildup. They’re non-electrical sparking too, which
makes them ideal for use in potentially explosive environments
– places where you couldn’t even consider electricity.
bWARNING: Gast Air Powered Gear Motors 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 gear motor
with all the right options
Pictured: typical right angle, 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.
