Roof ventilation units

Roof ventilation units are often used to ventilate and/or extract smoke and heat from liftshafts. However, they can also be used very well on the roof of stairwells, factory halls and warehouses as N-SHEV system and/or for daily ventilation purposes.

The main advantage of roof ventilation units is the very limited influence of wind force and wind direction on the ventilation capacity. This makes these units very suitable for use in natural smoke and heat extraction systems.

Our roof ventilation units can also be supplied with insect mesh as an option.
Other sizes are also available on request.
