Blauberg Extero EC

Extract ventilation systems installed in various premises.External wall mounting from outside.Compatible with Ø 100 up to 200 mm round air ducts.

Steel casing with a special polymer atmospheric resistant coating.Special design of the casing protects the motor against direct sprays of water.Back side has a special sealant for tight contact and adaption to the wall.Vertical air exhaust downwards through a protecting screen against birds and rodents.The connection spigot is equipped with rubber seal.

The fan is controlled with a 0-10 V external control signal speed controller for EC motors.The fan air capacity could be regulated by various parameters, including temperature level, pressure, smoke, etc.When a control parameter changes the EC motor changes its rotation speed to provide the best suitable air flow.The fans with EC motors can be integrated into a building management system or similar systems to adjust ventilation system with respect to specific user's demands.

High-efficient direct current EC motor with external rotor and backward curved blades.EC technology meets the up-to-date requirements to energy-saving and controllable ventilation and provides up to 35 % energy saving as compared to asynchronous motors.EC motor ensures totally controllable speed range for the fan and has integrated overheating protection with automatic restart.The turbine is dynamically balanced.The fan is compatible with 50 Hz and 60 Hz power mains and the maximum speed does not depend on power mains frequency.

Vertical mounting on external walls of buildings and premises.Flexible air duct is fixed on the fan spigot with a clamp.The fan with connected air duct is fixed at the wall on a mounting plate. Power supply through the external terminals. After mounting of the ventilator a protection cover is mounted over the mounting plate.
