Motor outside the air stream

All MUB/T fans have impellers with backward curved blades, manufactured from aluminium. The MUB/T fans are suitable for medium temperatures up to 120°C continuously. Motor protection by cold conductors or thermal contact, to be connected to an external motor protection device. The casing consists of an aluminium frame with fibreglass reinforced plastic corners and double skin, galvanised steel panels with a 20 mm mineral wool insulation. Panels are removable, allowing flexible ventilation solutions - the air direction can easily be changed by 90°. With quick lock access door. The MUB bottom panel is shaped as a grease tray and incorporates a pre-mounted 1" drain plug. An isolator switch is mounted on the casing.

Several filter modules like f.e. activated carbon- or aluminum filters are available, calculated individually on the working point.
