 How to Clean a Centrifugal Extractor Fan

  • Turn Off Unit

Your first step is not really something that should need to be said but for your safety of course remember when you are working with electricity to turn off all power

When it comes to working with electricity then you should remember that you have to take safety in account and switch off the power to your centrifugal extractor fans.

  • Lubrication of Bearings

With a centrifugal extractor fan, the blades help remove the air in the room but to keep it working you are going to need to keep on oiling the bearing and of course keeping the blades very clean.  There will usually be a label on your blades as to how you are supposed to be keeping your unit clean as well as being safe when you return power to the unit.  The label should be information saying when they should be cleaned and how often oil should be applied to the unit.

A lot of older fans don’t have self oiling bearings meaning you are going to have to do it from hand but if you have a newer model then you might have to get a replacement.

When you are cleaning your fan blades then they can be quite dangerous if you have not done this properly.  Most of your blades are going to be a little curved which will mean that your blade will probably be prone to getting more dirt attached to them that is why you need to make sure you clean them properly otherwise you are going to have a lot of problems when it comes to your fan.

You should be cleaning the blades regularly in fact but it won’t take you an hour but you have to be careful.  You should be cleaning each of the blades separately and thoroughly; many of the fans today will allow you to take out the blades completely giving them a more thorough clean.  It shouldn’t take that long to clean the blades but it is a good idea to clean regularly and properly, even if you get your unit checked out every year or so or six months just so you know that you are cleaning it right and there is no problems.

  • Reassemble Unit

This last part to finish off the cleaning procedure will be to reassemble the unit back together again.  All parts have to be returned to their original state in the fan; so before your blades can go back, everything else has to be put back into position.  Your fan blades will then go into place and make sure they are securely in their position.

Now you can enjoy your centrifugal extractor fan because there is nothing that is clogging up the airflow of your blades.

HINT: If you are unsure about when or how to clean your blades then many of the blades will have some warning labels on them which will detail you about cleaning them.
