A home is usually fitted with a bathroom fan, which can be with a timer or humidistat (or both), but now there's a way to have smart ventilation - a continuously running bathroom and kitchen fan!
They call them dMEV - decentralised Mechanical Extract Ventilation, and they comply with System 3 in the current Building Regulations.
We warmly recommend this continuously running fan - which can be placed anywhere in the house - since it is a single unit that can run both in the kitchen and in wet areas. It comes with an ultra-low energy DC motor and mixed flow impellor.
What is a dMEV Fan? How does it work?
A decentralised Mechanical Extract Ventilation Fan (dMEV) is commonly known as a continuous extract ventilation fan.
It provides a constant low-level background ventilation to wet rooms such as bathrooms, toilets, ensuites, kitchens, etc and it comes with a boost feature as and when it is required.
The fan is always ON - it is always running, and it provides five times more ventilation than intermittent fans, helping you protect against condensation and mould growth, for it ensures that quality air is always circulating.
The way a dMEV works - in particular, the Greenwood Unity dMEV, is by continuously extracting the air from the room it is installed at a low rate, and there's a boosting when required.
The boost function is either by an independent switch or automatically via humidity sensing, depending on how you set it up at installation.
The constant ventilation helps reduce steam and smells created by everyday activities such as cooking, bathing, and showering.
It helps promote effective ventilation which helps to create a healthy living environment and reduce the symptoms of asthma and other health conditions.

Set up and Control your Smart Continuous Ventilation Fan
The installation and setting up of this fan needs to be done by a qualified electrician, but it cannot be more simply. It can be safely installed in the kitchen, bathroom, utility room, WC/cloakroom, ensuite bath/shower room, etc.
The specific fan operation of this fan varies depending on the way it has been installed. You can have trickle speed (operating on a continual basis) or boost speed (activated manually using the GS2 switch or via the light room switch).
The TimerSMART monitors the length of time that there's an occupancy presence within a wet room (via the "switch-live") and provides a fixed over-run time period to best match the length of time that the "switch live" is active.
This removes nuisance running noise and unnecessary energy wastage typically associated with traditional timers.
The HumidiSMART monitors the ambient humidity within the wt room environment and looks for short peaks of humidity made either by showering or bathing.
It ensures that the fan is not on boost for prolonged periods of time, removing nuisance running noise and unnecessary energy wastage typically associated with increases to background humidity which naturally occurs with the changing seasons.
Set up the Greenwood Unity CV2 dMEV Fan - the Control panel
Via the Control panel, you can select at installation what settings you require. If the fan is in a bathroom, toilet, or ensuite, select the "Bathroom" option, and if it is in the kitchen, select the "Kitchen" option.
If you want it to run continuously, select the Trickle Mode, and if you need a boost, activate the Boost mode.
You can also select the HumidiSMART ON/OFF and TimerSMART ON/OFF via the buttons there.
