What is an exhaust fan?

A space that suffers from excessive heat or has a high exposure to moisture needs an effective exhaust fan. Some spaces such as kitchens, laundries, bathrooms, storage areas, garages, and workshops are naturally prone to contaminants and regulating air quality is critical. By nature, kitchens get hot. When cooking, there are emissions of heat, steam, fumes, and odours. Bathrooms and laundries are vapour zones that experience high levels of humidity and steam naturally penetrates spaces and cracks. Water in crevices is an excellent breeding ground for mildew and mold. Damp surfaces rot if unchecked. Prolonged rotting emits an unpleasant odor. Exhaust fans in humid rooms improve airflow by sucking out steam and vapor before condensation occurs. In hot spaces, they increase circulation keeping the rooms cool. ## Do you need an exhaust fan? There are certain conditions where the application of an exhaust fan is ideal. If you work in enclosed spaces, exhaust fans help suck out chemical vapours or dust that may be present. Venting moisture lowers the chance of the development of mould and mildew, which causes rots and unpleasant smells. Using an exhaust fan can aid some health conditions. Poor air quality conditions exacerbate Asthma and the presence of dust particles or fumes is also known to cause allergies. ## How to choose an exhaust fan Here are some features to look out for: ### Capacity of the exhaust fan An exhaust fan unit will deliver a given number of air cycles per hour in cubic meters. Its capability depends on the motor size and related mechanism. ## Installation categories Based on your specific needs, exhaust fans come in different types and range. A wall mounted exhaust fan is ideal where minimal installation work is required. They are installed on the wall and suck out humid or warm air through the ventilation system itself. ### Ceiling mounted Ceiling mounted exhaust fans are installed to the ceiling through an aperture in the attic of the building. The ducts of the fan exit through the roof. ### Inline systems Inline systems work best where natural aeration is difficult to achieve. The inline exhaust fan will be located in between the exhaust ducts. If you love simplicity in integration, look for an exhaust fan with a light. These freshen up the air and light up space simultaneously. The 3 in 1 range includes a fan, lamps, and heating. To eliminate the manual operation of the system, consider any with smart sensors. Such units automatically switch themselves on and off depending on user settings.
