But what exactly is an exhaust fan? How does it work? And what are the different types of exhaust fans available on the market?
This comprehensive guide will answer all your questions about exhaust fans, providing you with everything you need to know to make informed decisions about your home ventilation system.
Understanding Exhaust Fans: How They Work and What They Do
Exhaust fans are ventilation devices that work by drawing air from a specific area of your home and expelling it outdoors. They do this through a process called negative pressure ventilation, which essentially creates a vacuum within the space by pulling air out.
Here’s a breakdown of how exhaust fans work:
- Air Intake: An exhaust fan draws air from a specific room or area through a vent or opening.
- Air Movement: The fan uses a motor and blades to move the air through the ductwork and out of the building.
- Air Discharge: The air is discharged outdoors, typically through a vent on the roof or side of the building.
