Understanding Extractor Fans

Extractor fans are a type of mechanical ventilation system used to remove fumes, smoke, and other harmful airborne particles from a room or building. They are typically installed in kitchens, bathrooms, and other areas where air circulation is essential. In the UK, most extractor fans are either ceiling mounted or wall mounted and have an integrated light. When wired correctly, the light can be turned on and off independently of the extractor fan, which allows you to save energy by turning off the fan when the light is not in use.

Wiring Diagrams

Before you begin wiring your extractor fan and light, it is important to first understand the wiring diagrams that are used in the UK. These diagrams provide an easy-to-understand visual representation of how the wiring of your extractor fan will be connected to the various electrical components. It is important to familiarize yourself with these diagrams before beginning any wiring project.

Most wiring diagrams will include two main components: the circuit diagram and the junction box diagram. The circuit diagram will show the connection between the extractor fan and the junction box. This diagram will provide information about the circuit breaker, transformer, switch, and other electrical components.
