Example: Model designation: 1UP-NRV-10 Year manufactured: 2003

Gast Mfg. Corp. II 2GD c +1Cº Ta +40Cº Benton Harbor, MI USA Telephone: 269.926.6171

* Legend: II Equipment group II 2 Equipment category 2 G Gas atmospheres D Dust atmospheres c Constructional safety +1CTa +40C* Max. surface temp. 275ºF/135ºC

Ambient range +1Cº to +40ºC (34ºF/104ºF) Check the site environment for potentially explosive oils, acids, gases, vapors or radiation

Check the ambient temperature of the site and the ability to maintain proper ambient temperature. Ambient range: Normal conditions: 34ºF/1ºC to 250ºF/121ºC Hazardous conditions: 34ºF/1ºC to 104ºF/40ºC

Check the site to make sure that the air motor will be adequately ventilated and that there is no external heat input (e.g. couplings). The cooling air may not exceed 104ºF/40ºC.

Check that products to be driven by the air motor meet ATEX approval.

Check that the air motor is not damaged.

Improper environment, installation and operation can result in severe personal injury and/or damage to property.

Qualified personnel must perform all work to assemble, install, operate, maintain and repair air motor.

Qualified personnel must follow:

• These instructions and the warning and information labels on the motor.

• All other drive configuration documents, startup instructions and circuit diagrams.

• The system specific legal regulations and requirements.

• The current applicable national and regional specifications regarding explosion protection, safety and accident prevention.

INSTALLATION

Correct installation is your responsibility. Make sure you

have the proper installation conditions.

Injury Hazard

Install proper guards around output shaft as needed.

Air stream from product may contain solid or liquid material that can result in eye or skin damage.

Wear proper eye protection when installing this product.

Failure to follow these instructions can result in serious injury or property damage.

Page 3

Mounting

This product can be installed in any orientation. Mount the motor to a solid metal base plate that is mounted to

stable, rigid operating surface. Use shock mounts to

a reduce noise and vibration. Install a pressure regulator or simple shut-off valve to control motor.

Accessories

A muffler is shipped with the air motor (except 16AM) but is not installed. Consult your Gast Distributor/Representative for additional filter recommendations. Install a moisture trap and 5 micron filter in the air line ahead of motor.

Connection

Check the direction of the motor airflow. A single rotation motor will operate properly only in one direction. Single rotation motors require a sound absorber to be connected to the exhaust air port. Remove the plastic shipping plugs from the ports. Save plugs for future use during shutdown.

Install a 5-micron filter in the air line before the connection to the motor. Next install an air pressure regulator to control motor speed and torque.

Clean the compressed air connection with low pressure air to remove any dirt from the line before connecting to the ports.

Use the proper sized fasteners. For the most efficient output and control of speed, use air lines that are the same size as the motor inlet port if the connection is less than 7 feet (2 meters). For longer connections, use the next pipe size larger than the motor intake port. Connect lines to motor in the proper direction.

Air consumption data at various speeds and pressures are available from your Gast Distributor/Representative

r the factory.

OPERATION

Injury Hazard

Air stream from product may contain solid or liquid material that can result in eye or skin damage. DO NOT use combustible gases to drive this motor.

Wear hearing protection. Sound level from motor may exceed 85 db(A).

Failure to follow these instructions can result in burns, eye injury or other serious injury.

Check all connections before starting motor. It is your responsibility to operate this product at recommended speeds, loads and room ambient temperatures. Do not run the motor at high speeds with no load. This will result in excessive internal heat that may cause motor damage.

The starting torque is less than the running torque. The starting torque will vary depending upon the position of the vanes when stopped in relation to the air intake port.

Connect the sound absorber on the exhaust air port or valve connection.

Do not add any thrust to the end or side of the shaft when making connections.

Do not use a hammer on the shaft or connections.

Lubricating the drive shaft will make assembly easier. Use a puller for removal of pulleys, couplings and pinions on the motor shaft.

Check that the tension on the belt pulley matches the manufacturer’s specifications. Do not exceed the maximum radial and axial forces on the shaft. If the motor shaft is connected to the part to be driven without a coupling, check that the radial offset and axial force effect will not cause problems.

Use only belts with < 109electrical leakage resistance to prevent static electrical problems. Ground the motor.

Use a pressure regulator and/or simple shut-off valve to regulate the motor’s speed and torque. This will provide the required power and will conserve air. Open the air supply valve to the motor. Set the pressure or flow rate to the required speed or torque.

Operate the motor for approximately 2 hours at the maximum desired load. Measure the

surface temperature of the motor on the casting opposite the pipe ports. The maximum surface temperature listed on the motor is for normal environmental and installation conditions. For most air motors, the maximum surface temperature should not exceed 266ºF /130ºC. Do not continue to operate the motor if the measured surface temperature exceeds temperature listed on the motor. If your measured temperature does exceed listed value, consult with your Gast Distributor/Representative for a recommendation.
