Operation

If the rated current of the motor is exceeded during operation, the voltage and frequency of the power supply should be checked and compared with data on the unit rating plate. Some blowers can’t be operated over the whole range of the performance curve. Overload of the motor may occur due to excessive system back-pressure. In applications where over-pressure conditions may occur, a relief valve must be installed. The ring blower must not be subjected to shock or vibration loads.
