Fans with EC-motors www.systemair.com Photo: Scanpix Energy effi cient and environmentally friendly

2 The products in this leafl et are equipped with EC-motors. EC-technology is intelligent technology, using integral electronic control to ensure that the motor always runs at optimal load. What can EC achieve? EC-fans are favoured for their economical use of energy and simplifi cation of control. EC-fans are driven by energy-saving motors with electronic control (commutation unit) to keep them running in the optimal operating range. According to their design principle, these are synchronous motors, which run without slip and therefore no slippage losses occur. An excellent solution for demand...

4 • EC-motors, high effi ciency • 100% speed controllable • Speed regulator included • Integrated motor protection • Supplied with mounting bracket The K EC series is designed for installation in ducts. All the K-fans have minimum 25 mm long spigot connections. The fans have backwardcurved blades and external rotor motors (EC). The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibrations to the duct. The fans are delivered with a pre-wired potentiometer (0-10V), set to 10V from factory. This can easily be changed if the installation requires a lower...

6 • EC-motors, high effi ciency • 100% speed controllable • Speed regulator included • Low noise level • Integrated motor protection The KVKE EC models have a single inlet centrifugal fan with backward- curved blades and a maintenance-free external rotor motor (EC). These fans develop relatively high static pressure and have a very high effi ciency. The fans are delivered with a pre-wired potentiometer (0- 10V). The potentiometer is set to 10V from factory. This can easily be changed if the installation requires a lower duty. The KVKE motor and impeller are mounted on the access cover for easy...

8 • 100 % speed controllable • Integrated electronic motor protection • Modular system • Low noise level • Flexible air fl ow direction due to removable panels • Installation in any mounting position • Safe and maintenance free operation • Energy-saving The MUB-EC fans are driven by EC-external rotor motors. These are energy saving motors with high effi ciency. The power electronics are integrated in the motor housing. All models have one potential-free terminal for error message. All motors are suitable to be used for 50/60Hz. The input voltage for single phase units can vary between 200 and...
