AKU 315 EC

Acoustically insulated duct fans are made of galvanized steel. The fan casing has thermal and acoustic 50 mm insulation. These products can not be exploited in explosive environment and they can supply/extract only clean air.
Centrifugal fans with EC motors with maintenance free ball bearings are used for the AKU EKO fans. Fans with EC motors are characterized by high efficiency and high static pressure. The equipment has easily opening cover. It allows easy maintenance. The continuous control of motor speed is optionaly provided. The speed of EC motors may be changed by connecting 10 kΩ potentiometer to the control circuit. At simplifies way the electrical connection is avoiding the need of expensive and large dimension speed regulators. The speed may be set via an external signal 0-10 VDC. The maximum motor current and the rated power supply voltage are marked on the data plate, attached to on the unit. Acoustically insulated fans can be mounted only indoors.
