The Combivent terminal provides combined high and low level ventilation for plant rooms devoid of an external wall, or where mechanical ventilation is undesirable. 

Designed to allow the vertical discharge of flue gases through a roof mounted unit, the Combivent terminal is fitted with louvres on all sides providing ventilation, in accordance with regulations.  

The units are internally divided into quadrants and the whole assembly passes from roof level down to the plant room ceiling. They can also be used solely for aesthetic purposes where conventional ventilation exists. 

The Combivent principle eventually gave rise to our Natural Ventilation range which today forms an integral element of our ecological range of products.
