An exhaust fan is a mechanical fan designed to remove stale air, heat, smoke, moisture, or odors from a room or enclosed space and release it outside. It helps improve air quality and keeps the environment cool and fresh.
Operation:
An exhaust fan works by rotating blades powered by an electric motor. As the blades spin, they create negative pressure inside the room, which pulls indoor air toward the fan. This air is then pushed out through a duct or directly outside. As air is removed, fresh air naturally enters the room through doors, windows, or vents, creating continuous ventilation.
Exhaust fans are commonly used in kitchens, bathrooms, factories, and workshops to control heat, humidity, and fumes.
