Description
Fans using the EC technology are characterized by low energy consumption and simple control. The fan speed can be controlled by a 0-10V signal depending on requirements on air performance and highly efficient operation. To achieve the same air flow, the EC motor fan uses less energy than a conventional AC motor fan. The EC motors not only achieve energy savings at maximum speed, but also at lower speeds. In this case, the difference in energy consumption between an EC motor fan and a conventional AC motor fan will be even more considerable. The reduced energy consumption then guarantees lower operating costs.
Housing The housing is made of galvanized sheet steel. To facilitate servicing and maintenance, the motor and impeller are mounted on a tiltable door.
Impeller The impeller is radial with backward curved blades.
Motor The fan is equipped with a highly efficient energy-saving EC external rotor motor.
Noise level Sound pressure level is measured at a distance of 3 m (20m² Sabine)
Speed control The motor speed is 100% adjustable by a 0-10V signal. The fans have a built-in potentiometer in the terminal block, which makes it easy to find the selected operating point.
