1. Fluid used: Air 2. Fixed pressure: 6kg/cm² 3. Maximum operating pressure: 7kg/cm² 4. Ambient temperature: 0~80℃ 5. Lubricating oil: Clean 30" machine oil is required. 6. Continuous use: Possible (but not at high speed) 7. Recommended operating speed: Below maximum speed × 0.8. A. If the stirring shaft and stirring blades of the pneumatic motor mixer are not concentric, it can cause poor operation or failure. B. The main cause of failure in pneumatic motors is the entry of water vapor or dust; before piping, compressed air must be used to clean the inside of the pipes, and care must be taken to ensure that cutting powder, sealing tape fragments, dust, or rust do not enter the air pipe. C. Auxiliary machinery for pneumatic motors (air filters, air regulators, air lubricators, flow valves, etc.) should be installed as close to the pneumatic motor as possible. D. Air supply lines must be equipped with air filters, dryers, air lubricators, etc. (Lubricating oil should be clean 30" machine oil, supplying 1-2 drops per minute). E. If air pressure is supplied directly, there may be fluctuations in pressure, making it impossible to obtain stable horsepower, torque, or RPM; therefore, an air pressure regulator must be used. F. The diameter of the air pressure machinery (air filters, air regulators, air lubricators, control valves, etc.) must match the air consumption of the pneumatic motor. G. The control and stability of the pneumatic motor's speed must be adjusted from the air supply side; this way, there will be no back pressure on the exhaust side. H. During trial operation, use the air regulator to slowly increase the RPM to the required level; prolonged high-speed operation can damage the pneumatic motor and reduce its lifespan. Pay attention to using the correct pressure. During maintenance checks, it is important to note: A. The air lubricator on the air supply line must also be checked regularly; if it has decreased, it should be replenished.
