High efficiency fan
Low sound level
Easy installation & maintenance
STEC non-insulated roof fan is designed to be used for the extraction of exhaust air and other non-aggressive gases where low energy consumption, simple construction and demand controlled ventilation are required. It can be installed directly on the concrete or alternatively on a roof curb. The existing unit can be exchanged by using an installation frame, which is always included as standard in the delivery of STEC roof fan (sizes 225 - 630).
STEC is equipped with high efficiency EC-motors with integrated speed controller. The plastic impeller is optimized for high efficiency. The casing and motor-impeller-combination can be opened for easy service and maintenance. The fan discharges air vertically.
