How can we effectively reduce noise levels in air movement for specialized ventilation systems, such as those in hospitals, schools, offices, and laboratories? One of the most important factors is optimizing the structural design to minimize airflow noise. Another critical aspect is operating the impeller according to its specific airflow needs.
The below is calculation of noise level deduct when EC box fan run in variable speed.
This is noise level formula from impeller speed.
Air Flow rate percentage | 100% | 75% | 50% |
AC motors ON/FF control | M dB @ 4 fans on | -2 dB @ 3 fans on, 1 fan off | -3 dB @ 2 fans on, 2 fans off |
EC motor Variable speed control | M dB | -10 dB @ 75% speed | -15 dB @ 50% speed |
So, the EC motors driven impeller can give best solution in noise control.
