Centrifugal fans use a rotating impeller to accelerate air radially outward, generating higher pressure suitable for ducted systems with resistance. Axial fans use propeller-like blades to move air parallel to the shaft, providing high volume flow at lower pressures. The choice depends on system requirements: centrifugal for high pressure, axial for high flow.
Determine required airflow (m³/h) and static pressure (Pa) based on system resistance. Consider fan speed, motor power, voltage, frequency, and environmental factors like temperature and dust. Use the reference ranges provided and verify with the manufacturer for the specific model.
Regularly inspect for wear, imbalance, and cleanliness. Check bearings, belts, and motor condition. Monitor noise and vibration levels. Follow manufacturer's maintenance schedule and replace worn parts promptly to avoid failure.
Unusual noise, excessive vibration, reduced airflow, overheating motor, or increased energy consumption. If any of these occur, shut down the system and inspect. Verify that the fan is operating within its specified parameters and consult the manufacturer if issues persist.
