AMERICRAFT MANUFACTURING

What steps should be taken to ensure the proper installation and functioning of Americraft exhaust fans, blowers and coolers?

• Ensure the tightness of all fasteners, including foundation bolts, set screws within the fan wheel and V-belt drive.
• Verify that access doors are securely closed and effectively sealed.
• Examine the bearings to confirm their alignment and lubrication.
• Rotate the assembly manually to verify that it does not make contact with the housing. If the fan wheel strikes the housing, potential damage, shaft misalignment or bearing displacement may occur during transit. Necessary adjustments must be made before start-up.
• Validate the motor to ensure it operates at the correct speed and adheres to electrical characteristics
• Pay particular attention to connecting a single-phase motor solely to a single-phase power supply with the correct voltage and a three-phase motor only to a three-phase power supply.
• Assess the alignment of the V-belt drive, ensuring it is properly positioned and functioning effectively.

How do I know if the capacity or pressure is below the rating as mentioned?

If the capacity or pressure is below the mentioned ratings, following issues can be seen.

• Speed is too slow.
• Air leaks in the system.
• Damper not properly adjusted.
• Incorrect direction or propeller rotation.
• Total resistance of the system higher than anticipated.
• Poor fan inlet or outlet conditions (elbows, restrictions).
• Damaged propeller.
• Fan not properly selected for a high-temperature and / or high-altitude application.
• Propeller mounted backward on the shaft.

How to install industrial exhausts, ventilation exhausts and supply fans / accessories?

• When installing fans, ensure they are fixed to a flat, level and sturdy structure. Use shims as necessary to achieve precise alignment. This guarantees that the fan remains consistently aligned, operates smoothly without vibrations and reduces long-term maintenance expenses.
• If you are setting up floor-mounted fans, it is advisable, whenever feasible, to use poured concrete foundations. This approach provides a stable and robust foundation for the fans.
• For fans placed above ground level, it is essential to securely mount them on a structural platform. Furthermore, position these fans as close as possible to a solid wall or column to enhance stability and structural support.
