MUB Insulated duct fans

Efficient fans for supply or exhaust ventilation systems

Acoustic and thermal insulation 30 mm
Flexible airflow direction due to removable panels
Indoor and outdoor installation
Modular system of accessories
Available with AC and EC motors for 50 and 60Hz

Flexibility

The MUB 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.

Modularity

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.

Performance

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

Noise

The casing of MUB fans have a perfect acoustic and thermal insulation capacity.

Construction

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 fans are designed for straight through airflow but can easily be rebuilt due to removable panels for 90° air discharge.

Impeller

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

Motor

Depending on the type, MUB fans are equipped with AC or EC external rotor motor. Motors are suitable for 50Hz and 60Hz.

Motor protection

Depending on the type, AC motors have an integrated thermal protection with manual (electrical) reset, prewired integral thermocontact TK or thermistor PTC with leads to a motor protection device.

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

Control

EC motors with built-in potentiometer to adjust working point can be also controlled by external signal 0-10V.

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

AC motors can be controlled by 5-step, stepless speed regulator, D/Y switch or frequency converter.

Installation

The MUB 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.
