Bathroom Extractor Fan
Our bathrooms are not as spacious and airy as other rooms. Hence, they become highly humid after a hot shower. This moisture can produce mold and odors over a long time. Moreover, the walls of the bathroom can become damp and paint can start peeling. However, a bathroom extractor fan is the best solution to all these problems. It pulls out excess moisture from the bathroom and improves air quality.
Not to forget, all inline extractor fans are not the same. Some are perfect for small homes, while others work best in industrial and commercial bathrooms. You can feel confused with so many options. Hence, we have researched for you. This guide breaks down everything you need to know.
Importance of Bathroom Extractor Fan
Bathrooms are humid spaces. Hot water moisture builds up every time you shower. This moisture produces unpleasant odors. Moreover, this moisture can peel paint and warp materials over time. The best part is that an extractor fan solves this problem because it pulls out moisture. Additionally, the fan replaces it with fresh air.
Types of Bathroom Extractor Fans
There are several types of bathroom extractor fans.
-
Axial Bathroom Extractor Fans
Axial fans are the most common type of bathroom fan. They pull air straight through the fan in a linear direction. Note that these fans are lightweight, affordable, and easy to install. Thus, they are ideal for small and medium-sized bathrooms.
Pros:
- Quiet operation.
- Energy-efficient.
- Perfect for residential bathrooms.
Cons:
- Not suitable for large spaces or long duct runs.
- Less effective in high-humidity environments.
-
Centrifugal Bathroom Extractor Fans
They are more powerful than axial fans. Centrifugal bathroom extractor fan draws air in and pushes it out at a 90-degree angle. It does so through a rotating impeller.
Pros:
- Handles longer duct runs efficiently.
- Ideal for industrial bathrooms and commercial bathrooms.
- Better performance in high-humidity areas.
Cons:
- Slightly noisier than axial fans.
- More expensive.
-
Circular Bathroom Fans
Circular fans are round axial fans. They blend well with modern bathroom aesthetics.
Pros:
- Sleek design.
- Easy to install in closed spaces.
- Affordable.
Cons:
- Limited airflow compared to centrifugal fans.
- Not ideal for large bathrooms.
How to Select the Right Bathroom Extractor Fan
You should follow the factors below to get the right bathroom exhaust fan.
-
Air Extraction Rate
The extraction rate counts how much air the fan can remove in an hour. A small bathroom needs a fan with a lower rate. Whereas larger bathrooms require a higher rate to remove moisture effectively.
- Small bathrooms: 15-30 l/s (liters per second)
- Medium bathrooms: 30-50 l/s
- Large bathrooms or commercial spaces: 50+ l/s
-
Noise Levels
The noise level is measured in Decibels – dB.
Bathroom fans should be effective yet quiet. Noisy fans can be irritating in quiet homes.
- Silent fans: 20-30 dB
- Standard fans: 30-45 dB
- Powerful commercial fans: 45+ dB
Therefore, you must choose a fan with a lower noise rating.
-
Energy Efficiency
Energy-efficient fans help lower electricity bills. You must look for models with these specifications.
- Low wattage to reduce power consumption.
- Timer functions to switch off automatically.
- Humidity sensors turn the fan on and off as needed.
-
Timer and Humidity Sensors
A timer allows the fan to keep running after you leave the bathroom so that all moisture is gone. Humidity sensors are even better. They detect moisture levels and turn the fan on and off automatically.
These features improve air quality and save energy.
-
Water Resistance (IP Rating)
Since bathrooms are humid, the fan should have a good IP (Ingress Protection) rating to resist moisture.
- IPX4 is suitable for general bathroom use.
- IPX5 or higher is better for areas close to showers or bathtubs.
A higher rating ensures durability and safety.
-
Special Features for Added Convenience
You should try to purchase modern bathroom fans that come with extra features. This is because these features add convenience to your bathroom.
- Fans with built-in lights replace existing light fixtures.
- Heater-equipped fans add warmth after showers.
- Motion-sensing fans automatically switch on when someone enters the bathroom.
- Bluetooth-enabled fans to play music.
Conclusion
A good bathroom extractor fan keeps your space fresh and dry. It removes moisture and improves air quality. If your space is small, an axial bathroom extractor fan will work well. If you need powerful ventilation for a large or busy bathroom, an industrial bathroom fan or commercial bathroom fan is your best bet.
