decentralised mechanical extract Ventilation

Decentralised Mechanical Extract Ventilation (dMEV) systems consist of individual fans installed in specific rooms, typically wet rooms such as bathrooms and kitchens, as well as other areas prone to high humidity, like utility rooms.

These fans operate continuously to reduce indoor air pollutants and humidity, helping to prevent condensation-related issues like mould growth.

Decentralised Mechanical Extract Ventilation units that run continuously on trickle, then boost their speed when rooms are occupied or moisture rises.

WHAT IS DECENTRALISED MECHANICAL EXTRACT VENTILATION (dMEV)?

dMEV is the opposite of centralised (MEV) ventilation and uses a fan, in each room needed. Decentralised ventilation provides a constant level of ventilation which considerably improves air quality in the home. When the unit detects moisture, it boosts the speed automatically.

Why is dMEV so good?

Highly efficient

The EC motors are designed for continuous running and feature high-quality ball bearings.

They provide a very low power consumption.

Trickle and boost for all rooms with Intelligent humidity sensor

Our dMEV’s feature trickle ventilation that maintains a constant low level of ventilation, ensuring a fresher environment even when you’re not actively using the space.

When the built-in humidity sensor detects moisture in the air stream, it boosts the airflow effectively removing pollutants and excess moisture.

Low noise

Our winglet-type impellers feature a unique design with enhanced aerodynamic properties that effectively reduce noise while increasing efficiency.

Extra control

If you want even more control, you can add additional sensors for occupancy such as a PIR, additional humidity or a manual override.
