What is dMEV?

dMEV or Decentralised Mechanical Extract Ventilation, is a low energy, usually compact, continuous running fan, designed to promote good air quality in the home.

Decentralised simply means they are not designed as a single central whole house ventilation system such as MEV or MVHR systems. Instead, dMEV units can form part of your overall ventilation strategy along with, for example, PIV systems. However, due to their range of features, they can readily be used to replace standard intermittent fans.

Quieter and more energy efficient than standard extractor fans, dMEV units are a popular choice for both new build properties and renovations alike. dMEV units are particularly good at dealing with mould, damp, and condensation problems, by managing humidity and providing a constant movement of air in the home.

Let’s look at an example:
New to the market, the Monsoon dMEV range is designed to be a perfect fit within kitchens, utility rooms, and bathrooms.
With a switched live connection to control the boost speed, the unit incorporates a high-pressure axial impeller, which offers near silent operation, as low as 13dB on its lowest trickle setting.
The DMEV100HT model boasts a startling array of settings including:

• Optional intermittent or constant running modes,

• Optional over-run timer mode with comfort mode to prevent nuisance activations for
short bathroom visits

• Two different optional humidity functions: Ambient Response Humidistat with Rapid
Rise Detection

• Adjustable boost and trickle speeds in 1l/s increments

• Easy installation and commissioning, along with a simple LED programming
interface

• An impressive 126m3/h of extraction on its highest boost setting

• IPX5 rated for zone 1 installations

• Integrated UKAS calibrated airflow sensor

The unit’s party piece however, is the constant volume mode. This clever function automatically adjusts the fan speed to maintain the desired airflow.
If you set the fan to extract at, say 15l/s, then the fan will determine the most efficient mode of operation. Should the wind pick up outside, causing a rise in pressure through your ducting, the fan will automatically speed up to cancel any drop in the extraction rate. Again, should the pressure fall through the ducting when the wind drops, the fan will slow down to the optimum speed to keep the constant extraction level. Clever huh?
Manufactured in the UK and with a 5 Year warranty, the Monsoon dMEV is an excellent option if you are looking for a no-nonsense, function packed dMEV unit.
