Due to the elimination of an electric motor and the speed of the low weight fan/turbine assembly the noise level of the AQUAFAN cooling tower is very low. Positioning the drift eliminators above the fan/turbine assembly is responsible for an even further reduced noise level. The Noise power Level (SPL) of one unit at the maximum operational level does not exceed 80 +/-2 dB(A). Within 10 meter/yard of the tower this is < 58 dB(A)
