For installation in production facilities, public buildings and laboratories, in systems for cooling, heating, ventilation, cooling of electric motors, electronic equipment, etc.
Mechanical throttle flow adjustment is not recommended. If the output is fully closed, the fan will develop maximum pressure and zero flow. A measured increase of the consumed current by 7-10%. Considering its reduced cooling during this mode of operation, there is a possibility of overheating and irreversible damage to the engine, which may result in the failure of its warranty. The fan flow can be adjusted with a suitable electronic regulator.
The fan is not allowed to operate under vacuum conditions (for example, the blower can take air out of a room that can not get enough air otherwise). This will result in insufficient airflow to cool the motor and the fan will be damaged.
It is possible to adjust the fan speed by means of a frequency inverter or by phase adjustment with a reduction of the speed up to 75%. The fan can not be powered by a DC / AC inverter with a modified sinewave - this will cause it to malfunction.
