How do Extractor Fans work?

There are many different types of extractor fans, but they all pretty much work in the same way. Extractor fans work by using a motor to power an impeller that spins at high speed and blows air outwards, which creates a vacuum effect. This means that any particles or moisture will be pulled out of the air into the fan itself, so it can then be released outside through vents or pipes.

These powerful machines are used for everything from kitchen extractors to bathroom ventilation systems as well as industrial purposes such as drying machines and cooling towers. This blog post will explore what these fans do and how extractors fans work so you can make sure you get one that suits your needs perfectly.

What does an extractor fan do?

An extractor fan is a type of fan that pulls or extracts air from the hot or humid places in your house and dumps it outside. They’re usually located near kitchen appliances, bathrooms, washing machines, dishwashers, or other areas where there’s excess moisture due to steam from showering or cooking food etc. How they work depends on which fan you get and how it is installed or fitted. 

Ducted and Non-ducted Extractor Fans

There are two types of extractor fan fitting – ducted and non-ducted.

A non-ducted type of extractor fan is best for small bathrooms and can be installed in as little as 15 minutes without the need to use any screws or tools. This type of fan is ideal for a bathroom that doesn’t have much in the way of obstructions and can be placed on any flat surface – such as the wall, cabinet or floor.

A ducted extractor fan requires more work to install but does offer greater power than a non-ducted extractor fan so it’s best for larger rooms and applications with high ceilings like kitchens and living areas for example. A ducted extractor fan as the name suggests uses ducting as a means to expel the air. Ducting is simply a material used as a kind of pipe or pathway that the air travels through to outside.

Do extractor fans need to vent outside?

Yes, it is always a good idea to have your bathroom extractor fan vent outside. Remember the purpose of an extractor is to remove moisture and humidity from the air. If you simply deposit it in another room or the attic, for example, you are just moving the problem to another area. This could result in mould and damp building up.

How does an extractor fan work in a bathroom?

Bathrooms are one of the most humid rooms in your home, and when we say “bathroom” this can also include shower rooms and toilets too. Because these are rooms that are used every day, they need a decent extractor fan to expel moisture and unwanted smells.

Typically in a bathroom, extractor fans are activated by an overrun timer. An overrun timer activates the extractor fan via a light switch and stays on for a few minutes after you have left the bathroom or turned the light switch off. This ensures that any moisture, humidity, and unwanted smells have been extracted.

Does a bathroom fan help with smell?

Yes, as well as moisture, extractor fans are used to remove unwanted smells too. As well as bathrooms and toilets, extractor fans work great in kitchens too which is another room that requires the removal of all the different smells generated from cooking.
