The fan can be ideally positioned on a north dealing with wall to maximise exposure to the solar. A good compact solution to ventilating a shed, greenhouse or even a sub flooring space. It facilitates the drying up of damp or moist areas in the sub-ground area as a result of dry air is continually being blown over them.
With a brick-veneer house on a timber suspended ground we frequently discover the back of the steel air vent is blocked by the ground bearer as a result of the vent is positioned too excessive on the exterior wall. As nicely, the follow of using ‘slit bricks’ (bricks on their sides with a gap between them) rather than the builder putting in proper air vents just isn't beneficial as a result of the small opening between the bricks blocks up.
