Why use a Gast Air Motor?
Operate in All PositionsMount 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 StartsBecause Gast Air Motors go to work with air-cushioned smoothness, they cut stress on your equipment.
Self-sealing VanesVanes are self-sealing and automatically take up their own wear, thus ensuring con stant output for thousands of hours of use.
Mounting FlexibilityFoot, hub, face, NEMA-C, or metric flange motor mountings are standard equipment for most air motor sizes.
Four-vane or Eight-vaneFour-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 AccessoriesTo 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 ReversibleA 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 RunningAs 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 PortableGet maximum horsepower with minimum size and weight.
Minimum MaintenanceYou 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 OutGast Air Motors can be stalled or overloaded for long periods without damage.
Low PriceCost 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. SpeedThe output power of an air motor is relative to speed and to air line pressure.
Torque vs. Speed1. 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. SpeedAir consumption increases as speed and air pressure is increased.
How to Selectan 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• 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 ReliableLike 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 FlexibilityGast'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 ResistantBecause the body, rotor, and end plates are specially treated, these air motors can tolerate unfavorable moisture-laden conditions.
• No Oil ExpensesIf you are using several quarts of oil throughout the year, you'll eliminate that expense with non-lubricated air motors.
• No Periodic InspectionWith 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 HorsepowerSize 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 ControlYou 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 FlexibilityMore 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 ConfigurationsThat makes it easier for our product to work in your product. Our Gear Motors are available in four mounting configurations.
• More LifeUnlike 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.
