Overview
The Solo SELV 12 range has been developed specifically for complete safety in the 'splash zone’ of a bathroom and shower room for those rooms, usually internal, that need to have the exhaust air ducted some distance to an external discharge point. A single inlet impeller has been designed for maximum performance and minimum noise levels. The grille ensures efficient air management and incorporates a filter that can be removed for cleaning without dismantling the fan.
Suitable for wall, panel and ceiling installations and windows up to 25mm thick. For high rise or coastal applications, install through the wall with a Vent Cowl (Stock Ref No. 56 14 03). With a powerful SELV motor and proven, high efficiency centrifugal impeller, Solo SELV 12 can be used with 100mm diameter smooth bore duct in straight runs equal to 50m, yet still meets the 54m3/h (15 l/s) required by the Building Regulations Document F for ventilation of bathrooms.Solo SELV 12 can also be used with System 25 flat ducting for shorter concealed runs that benefit from its ultra slim 25mm depth.
The safety isolating transformer, to BS EN 60742, is mounted in a purpose made enclosure. The enclosure can be wall mounted or sited in the loft. The enclosure will accept mini trunking.

Manufacturers of some fluorescent/low energy lighting systems indicate that these can interfere with other electronic/timing circuits. For reliable operation of these circuits we recommend therefore that a tungsten filament light is used.
