The stylish Manrose commercial series internal louvre incorporates the internal shutters which are built into the grille so the internal profile of the fan is less obtrusive. These elegant and stylish units will blend into the background and cover a wide variety of commercial applications such as pubs, restaurants, hotels, offices, shops and factories. They are also suitable for use in public sector areas such as service stations, hospitals, schools and railway stations and are designed for heavy usage. Available in a soft neutral grey or traditional white, they will blend in with most decors and surroundings. Another feature of the range is that on the grey models the external grille is moulded in a dark grey so it will not be too obtrusive on the window line, and blend into the background. The grey commercial series does not require as much cleaning as their white counterparts. These fans are double insulated and do not require an earth. All wiring must comply with the current IEE
