Ensure regular maintenance of your roof axial fan’s impeller. For safe, reliable operation and to improve lifespan, its care is paramount in the utilization of this negative pressure roof axial fan.

Therefore, please pay due attention during fan operation. Ensuring impellers remain free from defects such as cracking, wear, or dust accumulation at every checkup and when they become free, should be a priority. Regular cleaning of the impeller with steel wire brushes to eliminate build-ups like dust and rust scales is advised, as prolonged use can disrupt impeller balance and cause rotor vibration. Following impeller repair, re-balance is necessary.

If feasible, make use of portable dynamic balancing machines on location for balance. Prior to balance, ensure all fasteners are tightened. Over time, these could loosen due to inequitable stresses on the impeller.

While roof axial fans are user-friendly, maintaining them is essential. Proper upkeep ensures their seamless functionality.
