The Importance of IP Ratings for Bathroom Extractor Fans

An IP rating is a standard means of measuring the effectiveness of a bathroom extractor fan. But what do the ratings specifically mean? And is any IP rating okay for my bathroom extractor fan?

In this blog, we will share the importance of IP ratings for bathroom extractor fans.

To prevent mould, fresh air should always be introduced into your dwelling daily, as it helps to regulate temperature and reduce condensation. Introducing fresh air can be as simple as having a ventilation routine, or installing extractors or PIV systems.

Having an understanding of the uses and reasoning for ducting can be just the information you require in order to get the correct ducting to fit your needs. Knowing how their differences can save you any potential mistakes if you choose to set it up yourself.

I-Sells is here to provide the answers you require whilst also supplying you with all the information you need to combat mould and have a well-ventilated home.

What is an IP rating?

IP rating stands for Ingress Protection rating. It’s a standard measure used to indicate the level of protection provided against solid objects (like dust) and liquids (like water).

For extractor fans, the IP rating is crucial as they operate in a humid environment.

An IP rating consists of two numbers:

• The first number indicates protection against solid objects.
• The second number indicates protection against water.

The higher the number, the better the protection. Here are some common IP ratings you would find for an extractor fan:

• IPX4: Protected against water splashes from all directions. This is the minimum required for bathroom fans.
• IPX5: Protected against low-pressure water jets from any direction.
• IPX6: Protected against powerful water jets.

Note: While higher IP ratings offer better protection, an IPX4 rating is typically sufficient for most bathroom extractor fans.

Who conducts IP ratings in the UK?

IP rating tests are typically conducted by independent, accredited testing laboratories. These laboratories specialise in product safety and performance evaluation.

Some of the well-known organisations that offer IP testing services in the UK include:

• Nexia Scientific Ltd: Primarily focuses on providing testing equipment but also offers testing services.
• Intertek: A global leader in testing, inspection, and certification with a strong presence in the UK.
• Particle Technology: Specialises in testing large or heavy items and offers IP testing services.
• CSA Group: Has a laboratory in North Wales offering IP testing services.
• Product Approvals Ltd: Conducts IP testing up to IP68.

These organisations have the necessary expertise, equipment, and accreditation to conduct IP tests according to the specified standards.

It’s important to note that while manufacturers can conduct internal testing, independent laboratory testing is often required for certification and consumer confidence.
