Rectangular & Square Duct Fans
KE / KT - Rectangular Duct Fans
The KE/ KT models have impellers with forward-curved blades and external rotor motors. The motor and impeller are mounted on the access cover to facilitate easy maintenance. The casing is manufactured from galvanised sheet steel. To protect the motor from overheating the fans have integral thermal contacts with external leads for connection to a motor protection device. The fans can be installed in any position and are easy to connect using the DS flexible connections. The KE/KT fans have a pre-wired, integral terminal box. KE is single phase, KT is three phase.

KDRE/KDRD fans have an external rotor motor with a mixed flow type impeller. The KDRE/KDRD series is notable for its relatively high static pressure and high level of efficiency. The casing is manufactured from galvanised sheet steel. To protect the motor from overheating, the KDRE/KDRD fans have integral thermal contacts with leads for connection to a motor protection device. The fans can be installed in any position and are easy to connect using the DSK flexible connections.

MUB - Multibox Centrifugal fan
In-line discharge
to 90°
The MUB fans have impellers with backward curved blades, manufactured from aluminium except the 355 which ispolyamide. The MUB is equipped with external rotor motors or IEC standard 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. (* Power at Shaft)

To select duty:- Plot airflow in m3/hr, then read bottom table to get Dynamic pressure, which needs to be added onto your design static pressure to give Total pressure. Read off the RPM speed at which the fan will need to run and select the required motor size (move up to the nearest size as specified in previous pages i.e 0.25 0.37 0.55 etc. Typical fan Reference - KPB 9-9/0.37/1000 Please note that Resistance pressure is in mmH20 which x10 = Pa i.e 10mmH20 = 100Pa
