They are the standard answer on warehouses, factories, retail units and commercial kitchens, and anywhere there is no suitable external wall to extract through. We stock roof fans from Systemair, S\u0026amp;P, Elta and Vent-Axia from 150mm to 710mm, in single and three phase, on UK stock with next-day delivery.

Check the supply at roof level too: single phase suits the smaller sizes, and most larger units are three phase. For kitchen extract, the fan must be rated for grease-laden air and elevated temperatures.

Unlike a roof fan with its motor in the airflow, the CFHT560 keeps its motor out of the air stream and is rated for air up to +120°C, so it suits grease laden or hot extract that would shorten the life of a fan with the motor in the airflow.

It is three phase only, Elta list no single phase input drive for this size, and must run through an Eltadrive variable speed drive, so budget for the drive. For a ducted fan inside the building rather than on the roof, look at a high temperature box fan instead.\u003c\/p\u003e\u003ch3\u003eWhy choose this over alternatives\u003c\/h3\u003e\u003cp\u003eA roof mounted fan keeps the motor and the noise outside the building and puts the discharge high above the roof line. Unlike a roof fan with its motor in the airflow, the CFHT630 keeps its motor out of the air stream and is rated for air up to +120°C, so it suits grease laden or hot extract that would shorten the life of a fan with the motor in the airflow. The base can sit on a roof pitched at up to 15°, which can save building a level upstand.\u003c\/p\u003e\u003cp\u003eThe Clearflow range runs from 350 to 630mm.
