EC axial fans are high-tech and robust products. Due to the design on the permanent-magnetic construction of the EC motor with integrated electronic controller , they are energy efficient and, in combination with special propeller geometries, also extremely quiet. Due to their low noise level, they are suitable for both industrial and residential environments. Different EC motors can drive fans with a diameter of 300 mm to 1000 mm . The propellers are made of sheet metal or composite materials (PA or PP) with the addition of fiberglass. The built-in electronic EC fan drives provide a soft start, regulate the desired speed and ensure the continuity of acceleration and deceleration of the propellers. For this purpose, an individual electronic drive has a control input / output circuit, where it receives operating requests via MODBUS RTU digital serial communication and returns diagnostic information of the fan operating status (key component temperatures, status of detected power supply faults, other operating faults). In the case of simpler devices, it is possible to use a simpler analog control input to adjust the speed of the EC fan and an alarm signal contact to detect malfunctions.
