A Guide to Different Types of Exhaust Fans

An exhaust fan, also known as a ventilation fan, is a device used to remove stale air, moisture and odours from an enclosed space. It works by drawing in air from the surrounding environment and expelling it outside, thus removing the stale air inside and ventilating the room better. Exhaust fans are commonly used in areas such as kitchens, bathrooms, laundry rooms, store rooms and commercial spaces to maintain proper ventilation and prevent the buildup of moisture, mould and unpleasant odours.
