Smart Technology

The MUB CAV/VAV is equipped with a sensor-control module and complete connection for constant air flow. The system is completely pre-wired for easy operation and installation. Depending on the adjusted operation mode the controller can be used as sensor- or control module.

It is possible to choose between multiple operation modes, from constant pressure, constant air volume (factory set), or just display data.


The MUB CAV/VAV fans are intended to use for supply or extract air, designed to be installed in any position.

The MUB fans are designed for straight through airflow but can easily be rebuilt due to removable panels for 90° air discharge. The construction of the casing and thermal insulation permits outdoor and indoor use.


High performence impeller together with high efficient motors are designed to ensure high-level performance to minimize power consumption and maximize efficiency.


Thanks to variety types of accessories as flexible connections, dampers, roof, base frame, etc. it is easy to design any ventilation system according to your demand.

By using special modular systems, where some accessories as heaters, coolers, silencers, filters or carbon filters are built-in in the same type of casing, you can even design a simple supply or exhaust air handing unit.


The casing consists of a corrosion-resistant aluminium frame with fibreglass reinforced plastic corners of PA6; highly shock-resistant. Panels made of double skin galvanized sheet steel with 30 mm acoustic and thermal rockwool insulation.

The MUB CAV/VAV fans use radial impeller with backward curved blades. These are made out of high-performance composite material or aluminum, dynamically balanced and paired with corresponding EC external rotor motors.


MUB CAV/VAV fans are equipped with EC motors. Motors are suitable for 50Hz and 60Hz.

Motor protection

EC motors have an integrated electronic thermal protection including locked-rotor protection and soft-start.


The "constant pressure kit" which is included in the MUB-CAV/VAV the operation mode can be changed from CAV to VAV (constant pressure).

The fan is directly controlled with the 0-10V output signal of the sensor-control module.

EC motors, depending on the type are also equipped with ModBus communication or alarm signal.   


The MUB CAV/VAV fans can be installed in any position indoor and together with weather protection roof also outdoor. With mounted base frame the MUB fans can stand on floor.  For preventing vibration to the duct it is recommended to use flexible connections.
