Exhaust Fan
SUSTAINABILITY & URBAN DESIGNbeginner
Definition
Ventilation fan or exhaust fan — a mechanical fan that removes moist or polluted air from a room and exhausts it outside. Exhaust fans are used in kitchens, bathrooms, and laundries to remove humidity and odours. In Indonesian humid climates, exhaust fans are essential to prevent mould growth in bathrooms.
Example
An Indonesian bathroom uses a ceiling-mounted exhaust fan operated by a humidistat — automatically running when humidity exceeds 60% to remove moisture from showers, preventing mould on walls and ceilings.
