General Systemair thermo fans have been developed for the use in exhaust air systems where media with increased temperatures have to be transported. The special design allows a reliable operation also in systems with higher demands due to increased temperatures or polluted air, for example from kitchens, industrial ovens or in process air. Systemair range Systemair thermo fans are available in three different executions. The Multibox MUB-K variant masters higher demands due to the motor being separated from the air stream. Should regular maintenance/cleaning be necessary, the Systemair ranges KBT/KBR with swing out impeller/door assembly is the ideal solution. For roof exhaust installations we are offering our ranges DNV/DVNI with motor separated from the airstream. Systemair fans are suited to transport media with a continuous temperature of either 100 C or 120 C, depending on the range. Motors Thermo fans are equipped with IEC standard motors, with some exceptions speed controllable by voltage. All motors with protection class IP 54 and insulation class F. Motors with thermal contacts and extended leads for connection to a Systemair motor protection unit.

KBT 160-200 Max temperature of transported air 120 C Speed-controllable Integral thermal contacts Low sound level The KBT fans have impellers manufactured from galvanised sheet steel with forward-curved blades. The casing is manufactured from double-skinned galvanised sheet steel and is insulated with 50 mm mineral wool. The KBT fans have a swing-out door for easy inspection and service. The direction of the door opening can easily be changed from left to right at site. The fan is isolated from the casing via connectors and anti-vibration dampers are incorporated into the base frame.to protect the motors from overheating the KBT fans have integral thermal contacts with external leads for connection to a motor protection device.

Motors are outside the air stream. The casing consists of an aluminium frame with fiberglass reinforced plastic corners and double skin, galvanised steel panels with a 20 mm mineral wool insulation. Panels are removable, allowing flexible ventilation solutions. With quick-lock access door. The MUB casing is equipped with a grease tray under the impeller and a protection guard at the motor side. An isolator switch is mounted on the casing. All MUB-K2 motors (except 630D4) are D/ connected for two speed operation. Motor protection by thermal contacts, to be connected to an external motor protection device. Standard execution, seen in airflow direction: service door left, top outlet. The MUB-K2 fans are delivered to 90 air direction airflow.
