Developed to withstand the most extreme conditions, the Helios smoke exhaust roof fans are invaluable lifesavers in case of fire. Thanks to their dual functionality, they can be used for everyday ventilation, e.g. in assembly areas and sales outlets, in addition to smoke extraction. The vertical air outlet prevents damage to the adjacent parts of the building in case of fire. Due to their robust design, smoke exhaust roof fans are ideal for use in difficult operating conditions.
The standard integrated transport lugs facilitate transportation and positioning at the installation site. The isolator switch, which is easily accessible from the outside and for the electrical connection, is practical for installation.
