prio 450 3~ EC Axial circular duct fan, max 10,128 m³/h

EC technology is intelligent technology; using integral electronic control which eliminates the slip losses in the motor and ensures that the motor always runs at optimal load and guarantees that the proportion of energy utilized effectively is many times higher and the energy usage considerably lower compared with AC motors. EC fans are notable for their economical use of energy and excellent ease of control. They can be varied in speed to match the airflow demand, and operate at high efficiency levels. For the same air volume, they consume distinctly less energy than AC fan drives. Another special feature of EC fans is their energy-saving potential not only at full load, but especially at part-load. When operating at part-load, the energy used is much lower than with an asynchronous motor of equivalent output.Reduced energy usage guarantees a drop in operating costs. The fan have external rotor motor (EC) with a mixed flow impeller which reduces the external dimensions of the fan. This fan have a high capacity in relation to its compact design. Brackets are supplied with the fan to make installation easier. The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibration to the duct. The fan is delivered with a pre-wired potentiometer(0-10V) that allows you to easily find the desired working point. Motor protection is integrated in the electronics of the motor. The casing is manufactured from galvanised sheet steel.
