Energy efcient & environmentally friendly fans The products in this leaet are equipped with EC-motors. ECtechnology 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 simplication of control. EC-fans are driven by energy-saving motors with electronic control (commutation unit) ensuring optimal operating efciency. According to their design principle, these are synchronous motors, which run without slip and therefore no slippage losses occur. An excellent...

K EC, circular duct fans • • • • • High efciency in all areas of the fan curve 100 % speed controllable by 0-10V or PMW signal Easy adjustment of ventilation rate by installed potentiometer Electronic 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 backward-curved blades and external rotor motors (EC). The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibration to the duct. The fans are delivered with a pre-wired potentiometer...

KD EC, circular duct fans • • • • • High efciency in all areas of the fan curve 100% speed controllable Integrated electronic motor protection Supplied with mounting bracket Easy adjustment of ventilation rate by installed potentiometer The KD-EC series have external rotor motors (EC) with mixed ow impellers which reduce the external dimensions of the fans. The casing is manufactured from galvanised steel. These fans produce high capacity in relation to their compact design. Brackets are supplied with the fans to simplify installation. The FK mounting clamp facilitates easy installation and removal,...

KVKE EC, circular duct fans • • • • • High efciency in all areas of the fan curve 100% speed controllable Integrated electronic motor protection Easy adjustment of ventilation rate by installed potentiometer Low noise level The KVKE EC models have impellers with backward-curved blades and maintenance-free external rotor motor (EC). These fans develop relatively high static pressure and produce very high efciency. The fans are delivered with a pre-wired potentiometer (0-10V). The potentiometer is pre-set to 10V (factory default). This can be adjusted should the installation require a lower duty....

KVO EC, insulated circular duct fans • • • • • High efciency in all areas of the fan curve 100% speed controllable Integrated electronic motor protection Easy adjustment of ventilation rate by installed potentiometer Low noise level The KVO-EC motor and impeller are mounted on the access cover for ease of maintenance. The service cover can be easily removed by withdrawing the hinge pin. Motor protection is integrated in the electronics of the motor. The fans can be installed in any position and are easy to connect to spiral ducts using FK mounting clamps. The KVO-EC models are manufactured from...

MUB EC, square duct fans • • • • • • • High efciency in all areas of the fan curve 100 % speed controllable Integrated electronic motor protection Low noise level Flexible air ow direction due to removable panels Installation in any mounting position Safe and maintenance free operation MUB-EC fans are driven by EC-external rotor motors. All motors are suitable for 50/60Hz. The input voltage for single phase units can vary between 200 and 277V, for three phase units between 380 and 480V. Speed control by a 0-10V signal (MTP/MTV controller or EC-Vent). All models are equipped with impellers with...
