What is a dMEV fan?

 

Decentralised mechanical extract ventilation fans (dMEV), commonly known as continuous extract ventilation fans, provide constant low level background ventilation to wet rooms (bathrooms, kitchens, etc.), with a boost feature as and when required. Because the fan is always running it provides 5 times more ventilation than intermittent, helping to protect homes against condensation, mould growth and ensure quality air is always circulating.

​

How does it work?

 

dMEV fans work by continuously extracting air from rooms in your home at a low rate and boosting when required – either by an independent switch or automatically via humidity sensing. This constant ventilation helps reduce steam and smells created by everyday activities such as bathing, cooking and showering. It helps promotes effective ventilation which can help create a healthy living environment and reduce the symptoms of asthma and other health conditions.

 

What do I need to do?

 

dMEV’s are low maintenance, low energy, low noise, decentralised mechanical extract ventilation fans. The system is installed and set up for you. It will run in the background and boost when showering, cooking, etc. You may have an additional
means of manually boosting the unit by using a switch in your kitchen or bathroom. The unit MUST remain switched on at all times to keep moisture and Humidity levels acceptable.
