Winds of htf exhaust fan, htf exhaust fan, air conditioning and ventilation neutral

 Fans allow full voltage start or step-down start htf exhaust fan price, but it should be noted that the current full voltage starting about 5 to 7 times the rated current htf exhaust fan, voltage starting torque is proportional to the square of the current, when there is insufficient grid capacity, should start a buck. (When the power is greater than 11KW, should adopt the buck starts.) When the test Fire htf fan exhaust fan, you should carefully read the product manual, check the wiring method is consistent with the wiring diagram; should carefully check the operating voltage of the power supply fan meets requirements, whether the power phase or phase htf exhaust fan with a quote, with the capacity of the electrical components to meet the requirements. When the fan up to speed, the fan should detect the input current is normal, the fan operating current can not exceed the rated current. If the current exceeds the rated current is running, you should check the supply voltage is normal fan. Fan motor power required means that certain conditions, for centrifugal fan and wind chassis, the power required for the larger air intake fully open. If the inlet operated fully open, the motor may be damaged. When the fan blower test the best import or export pipeline valve is closed, will gradually open the valve operation, until the desired conditions, and pay attention to the fan operating current exceeds the rated current.
