The CF200 centrifugal fans use the latest technology to provide extremely powerful, yet very quiet and vibration free ventilation. The CF200 ranges are designed for bathrooms, toilets, cloakrooms, utility rooms. Designed to move air over long distances, these units will give maximum performance even against pressures caused by long lengths of ducting and resistance by grilles. All models are fitted with a built-in spring operated non-return flap into the discharge spigot to stop backdraughts. There are seven models in each series. The CF200 has an extract rate of 110m3/hr 31 litres per second. The units are all manufactured using high impact ABS thermoplastics for strength and durability, aesthetics and easy cleaning. Power to the CF200 range is provided by a single phase induction motor with pre-oiled bearings for a long, maintenance-free life. Designed to comply with the Building Regulations on Ventilation (F1).
