My inline fan isn’t working!
In line fans are a great addition to the home, especially those homes with windowless bathrooms or where the bathroom is a high traffic area! They are powerful, discrete and quiet. This makes them very flexible when it comes to fitting them with the decor and a great choice if space is an issue.
In line fans usually sit in the ceiling cavity or in the loft/attic depending on the space and location of the bathroom. They are very handy if your bathroom does not have an exterior wall (en-suite etc).
As good as they are, in line fans sometimes run into trouble. We will cover some of the more common problems in this post.
- The fan doesn’t seem to be extracting enough air!
If the fan isn’t extracting enough air it is almost always worth checking the extract rate of the fan and how complicated the ducting is. You can take a look at our post on figuring out the correct size of fan you need for your room here. You can see a comparison of the extraction rates of the various in line fans we sell below.
(68l/s on boost)
You can see that if you have a bigger room you are going to need either the MF100 or the ACM100. If you have a smaller ensuite then you might want to look at the CFD200 or the MAN50 models.
The other consideration is how complicated your ducting is. Most inline fans can work across about 5m of total ducting. However to ensure they don’t lose pressure (and negatively affect the extraction rate) that 5m is really only for fans like the MF100 and ACM100 which have higher extractions rates and work under higher pressures. All of the inline fans that we sell will extract better over complicated ducting set ups than a standard axial fan.
- The fan has stopped working
It is important to know why your fan has stopped working before trying to get it replaced because if there is a problem with the installation rather than the fan itself then you will just end up repeating the same mistake and having another fan fail. If you have had multiple in line fans and they keep failing it might be to do with how the fan is situated.
So make sure that your inline fan has been installed correctly. If it is condensation that is causing the problem then just replacing the fan won’t be enough.
These are the two most common problems with inline fans not working (other than a mechanical fault). If you are happy that everything is installed correctly and your fan still isn’t working then get it sent back for a replacement.
