The MUB fans size 499 have impellers with backward curved blades, manufactured from aluminium. The MUB 499 is equipped with external rotor motors, fully speed controllable. The three phase motors are D/Y connected for two speed operation.
Motor protection is done by thermal contacts, which have to be connected to an external motor protection device. The casing consists of a corrosion-resistant aluminium frame with fibreglass reinforced plastic corners of PA6; highly shock-resistant.
The double skin panels are manufactured from galvanised steel with 20 mm mineral wool insulation.
To avoid condensation the profile is provided with a separate chamber to fix screws. The Multibox fans are delivered for straight through airflow but can easily be rebuilt due to removable panels. This allows flexible ventilation solutions.
The MUB can also be used as extract- or supply air unit in air handling units. Installation in any mounting position is possible.
