Combivent

The Combivent terminal provides combined high and low level ventilation for plant rooms devoid of an external wall.

Where boiler house ventilation is difficult or where the aesthetics of the flue gas discharge must be minimised and in keeping with the building, the Combivent terminal provides architects and consulting engineers with an economical and efficient solution. The Combivent terminal is designed to allow the vertical discharge of flue gases through a roof mounted unit, fitted with louvres on all sides providing high and low level ventilation requirements in accordance with BS 6644:2011. These units are internally divided into quadrants and the whole assembly passes from roof level down uninterrupted to the interface with the plant room ceiling. The terminals are manufactured in high grade aluminium for square, rectangular or mitred designs and circular systems from fire retardant GRP. We are also able to supply bespoke designs to meet with architectural requirements.


The Combivent principle eventually gave rise to our Natural Ventilation range which today forms an integral element of our ecological range of products. This is another example of our ongoing policy of evolving and expanding our existing product range whilst looking for new areas where we can apply our knowledge and skills. This evolution is what keeps us at the forefront of our field.
