What power and type of in-line bathroom extractor fans should I be looking for?

We need to give every bathroom an extractor fan since it will help to extract the moisture from the air. As you know, our bathroom can easily become extremely humid. Therefore, it’s essential to decrease the humidity level to prevent damp problems.

If you let your bathroom have too much moisture, it can cause mold formations, wall damage, as well as different forms of structural issues. Luckily, there is a wide range of good bathroom exhaust fans out there these days.

Types of Bathroom Extractor Fans

Bathroom extractor fans come in three main types. They include centrifugal, axial, and inline. The least powerful type is an axial extractor fan. However, this type is fine for most situations. You shouldn’t duct these fans more than 2-3m. It’s best to install them on a wall that has direct access to the outside.

It is a good idea to consider a centrifugal fan if you want to duct your fan more than 2-3m. This type of bathroom extractor fan is more powerful in comparison to axial models. They are great for bigger bathrooms. Also, these fans are noisier.

Another choice is an inline fan. You can install these fans in the ceiling void or the loft. They are good solutions if you want ducting long distances. You can also install them out of the way. They are the most powerful type.

Benefits of Having an Inline Fan

Decrease Noise

Since the fan is installed further away in the roof space, this option can reduce noise. Moreover, if you have well-insulated roof space, you should consider buying an inline fan. These models are one of the quietest ventilation solutions out there.

High Power

Well, inline fans come in large sizes. They are constructed with very high power motors that you rarely find from a standard ceiling mounted as well as a wall-mounted extraction model.

Length of the duct run

These fans are designed to operate with ducting. Therefore, these models retain a better percentage of the advertised capacity than basic extraction ones. These fans are ideal for other applications as sub-floor ventilation and heat transfer.
