Decentralised Mechanical Extract Ventilation

An energy-efficient ventilation solution using small fans that run continuously. These fans are quieter than the intermittent versions and cost less to run. They also ensure good indoor air quality as they continuously extract the stale air out of the room and ensure it is replaced by fresh air.

A decentralised Mechanical Extract Ventilation (d-MEV) system is a low energy, continuous mechanical extract ventilation system designed to draw moisture laden air out of the wet rooms (bathrooms/utility and kitchen) providing a quieter and more efficient system compared to intermittent fans.

The Building Regulations Approved Document F gives examples of four main methods of ventilation. System 3, Continuous mechanical extract ventilation can be achieved using a single centralised extract unit such as the Sentinel Multivent ducted to ‘wet’ rooms (kitchen, bathroom, en-suite and WC) or by decentralised individual fans, such as the Lo-Carbon Response in the ‘wet’ rooms. The fans run continuously at near silent levels providing a simple and effective form of ventilation. SELV (Safety Extra Low Voltage) is designed for areas where a fan can be installed within Zone 1 in a room where there is a fixed bath or shower. Lo-Carbon Response is a continuous running, constant volume dMEV unit with switched live (LS) and innovative digital display. Quiet running and with high-pressure development, the Response is best in class. The attractive and discreet styling of the Vent-Axia Lo-Carbon Response will complement the décor of any new home while virtually silent operation ensures optimum ventilation is achieved without intrusive noise.

The Lo-Carbon NBR DMEV and DMEVe range have been designed for new build properties. The units are SAP rated and come delivered with 7 year warranty for peace of mind. The units are IPX5 rated, meaning they can be installed in Zone 1 in bathrooms. The NBR DMEV units are suitable for wet rooms, bathrooms, utility rooms and kitchens.
