Designed as a process ventilation unit for removing process loads, as heat loads, dusts, etc... Used as an extract air unit for extracting mode or as a supply air unit as displacement mode.

Installation in any mounting position is possible.

Construction of casing and thermal insulation permits outdoor and indoor use.


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.


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


The casing of MUB + FILTER models have perfect acoustic and thermal insulation capacity.


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 + FILTER fans use radial impeller with backward curved blades. These are from from high-performance composite material or aluminum, dynamically balanced and paired with corresponding external rotor motors or IEC motor with efficiency IE3.


Depending on the type, MUB + FILTER fans are equipped with AC or EC external rotor motors. 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.


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.


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


MUB + Filter comes with a built-in Coarse 65% (G4) panel filter.
