MUB fans have been equipped with bent-backwards, free-running fan wheels of polyamide and vol-tage-variable external rotor
motors. An exception is formed by the Multibox MUB 062 630 D4-A2, in which the speed variation is only possible by a frequency
inverter.
The 400V version is suitable for D/Y connection and makes 2-level operation possible (not with Multi-box MUB 062 630 D4-A2). An
internal thermo-contact with nished lines for connection to a motor protection device has been installed as an overheating protection
for the motors of the MUB fans.
The frame section of the housing comprises corrosion-proof aluminium with aluminium or alternatively plastic corners. In this way, the
highest possible impact resistance is guaranteed. The housing itself comprises double-shelled panels of galvanised sheet metal with a
20 mm mineral wool insulation.
For thermal decoupling, the side sheets have tabular rivets. As a default, the Multibox fans have been designed for a straight air
throughow. As a result of their replaceable elements, they can easily be retted. This permits exible solutions in the area of ventila-
tion. MUB fans can thus be used in the rack system area as air-feed or waste air devices.
The Multiboxes are suitable for the conveying of clean air, air with a low dust and grease content, me-dia up to a max. air density of
1.3 kg/m3 and an admissible moisture of max. 95%.
