Mounting an Extractor Fan
Sunday, May 8th, 2011Rooms in which condensation collects, such as utility rooms, bathrooms and kitchens, can benefit from having an extractor fan fitted. These fans suck up the moisture and direct it to the outside of the building, replacing it with dry air collected from other parts of the house. This will discourage the build up of mould on surfaces affected by moisture.
It is always possible to simply open a window, but heat will just be wasted by doing this, whereas an extractor fan will keep the interior at a steady temperature whilst removing the moisturised air and will be much more effective at doing so.
An extractor fan can be mounted into a window by cutting a hole in the frame, placed on a ceiling or mounted directly into an outer wall.
It is important to buy a fan that operates at the correct power for the job that it is required to do. The extract rate as displayed on the packaging will indicate the power rating, and as a guideline when choosing one you can figure that the average kitchen or utility room needs ten complete changes of air per hour.
Fit the outer grille into place first, in the opening you cut in the window frame and line up the gaskets. The inner mounting plate can then be fitted to the grille in accordance with the instructions included with the unit. It is usually better to have two people doing this, one on the inside and the other on the outside holding it in place. The main body of the fan is then fitted to the inner plate and screwed in place.
