Elta Fans has expanded its range to help landlords and installers comply with Building Regulations. It has added the MORI dMEV II 150HT to its de-centralised mechanical extract ventilation (dMEV) line-up, designed to provide ultra-quiet, low-energy ventilation for use in kitchens, utility rooms, bathrooms, shower rooms, en-suites and toilets.

The continuously running units aim to provide improved performance over intermittent extract fans for the existing homes market, as they supply a guaranteed ventilation rate and do not have a high dependency on background ventilators, such as trickle vents in windows.
Paul Harrington, Head of Residential Sales at Elta Fans, said: “For many years the most popular fans in the U.K. have been intermittent versions, which do nothing until they are switched on by the owner or occupier. They can be noisy and ineffective, explaining the rise in popularity of dMEV systems.

“Continuously running fans operate at what is known as a ‘trickle speed’. The Building Regulations specify the level this must be in order to ensure compliance and good performance, based on occupancy, floor area, and the number of bedrooms. For example, in a typical three-bedroom dwelling with 4 occupants and a floor area no bigger than 70m2, the continuous ventilation rate should be at least 21L/s – a level that can be difficult to reach for some dMEV models.

“The MORI dMEV II 150HT has a very high trickle rate of up to 29L/s (and up to 50L/s when on boost), which provides peace of mind that Building Regulations can be achieved, even in larger homes with high occupancy levels.”
