Model TEFC Motor Silencers

The major noise generated in a totally enclosed, fan cooled motor is the cooling fan. The fan located in the bell on one end of the motor draws air in from the atmosphere and discharges it over the cooling fins on the motor. The standard Aeroacoustic "Silentflow" electric motor silencer, Model EM will reduce normal TEFC electric motor inlet noise to below 90 dBA at 5 feet.
