Hybrid type, self-regulating centrifugal roof fans, low profile, horizontal outlet to fit directly to a circular duct for ventilating homes and small work spaces. Complying with the new Technical Building Code, for ventilating homes and small work spaces, centrifugal backward curved impeller in galvanised sheet steel protected by black polyester paint, an aluminium cover, galvanized sheet steel bird-proof guard, duct connection flange seal, an external rotor EC motor, thermal protection, and IP55 on-off switch, which can be moved away from the fan.
CTBH ECOWATT range fans start up automatically when temperature conditions do not permit sufficient natural air circulation.

Auto-adjustable cabinet fans made from galvanised steel, F400-30 certified for air extraction in event of a fire, furnished with a centrifugal direct-drive fan, with forward impeller.

Can be used in hygro-adjustable installations if the curve of the model is adapted to the requirements of the installation.

Can be installed outdoors as Standard (vertical discharge models require weatherproof covers).
