hen creating a comfortable and healthy home environment, it’s crucial for customers to choose the best bathroom exhaust fan. Not only does a good exhaust fan help eliminate excess moisture and odours in the bathroom, but it also plays a significant role in preventing mould and mildew growth.
Yet, choosing the right size and indeed type of fan can be difficult for some homeowners, especially with so many models available on the market. This means many will be looking to those in the trade to help them make the best purchasing decision.
Here at The Bathroom Showroom, we look at the most popular types of bathroom exhaust fans while recapping the key factors to consider when recommending the best fans for your customers.
What Types of Bathroom Exhaust Fans Are There?
There are three main types of bathroom exhaust fans including Axial, Centrifugal, and Inline.
Axial Fans: Axial fans are the most common type of bathroom exhaust fans and are relatively inexpensive and easy to install. They have a simple design with propeller-like blades that work by pulling air through the fan blades in a straight line, perpendicular to the axis of rotation. This design allows for efficient airflow and ventilation in the bathroom.
Pros:
-
Affordable and easy to install
-
Quiet operation
-
Energy-efficient
Cons:
-
Limited airflow capacity compared to centrifugal fans
-
Not ideal for long duct runs
Centrifugal Fans: Centrifugal fans, also known as radial fans, are more powerful than axial fans and are often used in larger bathrooms or bathrooms where homeowners prefer multiple showers or baths per day. Centrifugal fans use a rotating impeller to create airflow. Unlike axial fans, centrifugal fans pull air into the fan housing at a right angle to the axis of rotation before expelling it through the duct.
Pros:
-
High airflow capacity
-
Ideal for longer duct runs
-
Can be more powerful than axial fans
Cons:
-
Typically more expensive
-
Louder operation compared to axial fans
Inline Fans: Inline fans are installed in the ductwork outside of the bathroom, rather than directly above the shower or toilet. This design allows for quiet operation inside the bathroom while still providing effective ventilation. These fans are located outside the bathroom with ductwork used to connect them to the bathroom. Inline fans are often quieter than other types of fans and can be more efficient in moving air over long distances.
Pros:
-
Can be used for multiple exhaust points
-
Energy-efficient
-
Versatile installation options
Cons:
-
Requires additional ductwork for installation
-
May be more expensive upfront

Factors to Consider When Helping Customers Get The Best Bathroom Fan
-
Bathroom Size: The larger the bathroom, the more powerful the fan needs to be.
-
Ventilation Requirements: The number of showers or baths taken per day will affect the ventilation needs.
-
Fan Location: Consider the location of the fan. A ceiling-mounted fan is generally more effective than a wall-mounted one.
-
Noise Level: Some fans can be quite noisy. If noise is a concern, look to those fans that are quiet runners or reduced noise models.
-
Energy Efficiency: Energy-efficient fans can help reduce your customers' energy bills. Look for fans with a high airflow rate and a low wattage.
Additional Features:
-
Humidity Sensor: Some fans have built-in humidity sensors that automatically turn the fan on when the humidity level in the bathroom reaches a certain point.
-
Timer: A timer can be useful for ensuring that the fan runs for a set amount of time after a shower or bath.
-
Light: Some fans have a built-in light that can be used for additional illumination in the bathroom.
