FLUX DMEV 100 Constant Running Trickle & Boost Extractor Fan

The Elta FLUX dMEV 100 is a continuous running decentralised extract fan (dMEV) for bathrooms, toilets and other wet rooms. It trickles at as little as 18 m³/h (5 l/s) and boosts to 90 m³/h (25 l/s) when mounted through the wall, with a built in humidistat and intelligent run-on timer deciding when to speed up.Its single phase EC brushless motor draws from 1.0 W to 5.8 W and runs on ball bearings with integral thermal protection. It mounts on a wall, ceiling or window (window kit needed), is IPX4 on a wall and IPX2 on a ceiling, has a tool free removable front cover and carries a 5 year Elta warranty. 1 Phase EC Motor Up to 90 m³/h Speed Controllable What it is best used forBathrooms, en suites, WCs and utility rooms in new build and refurbished homes, flats and student or social housing where a continuously running extract fan is specified for Part F. Elta estimate it costs £2 to £3 a year to run around the clock (June 2023 prices), so it suits landlords who need ventilation that tenants do not switch off.It is designed for clean air only, so it is not for cooker hoods, grease or fume extract, and it must not discharge into a flue or hot air duct. When it is ducted from a ceiling the boost speed is limited to 72 m³/h, so for a large or busy bathroom with a long duct run look at a 150mm unit.Why choose this over alternativesAn intermittent bathroom fan only clears moisture while the light is on. The FLUX dMEV runs constantly at a quiet trickle and steps up on its own when the humidistat sees a sharp rise above 65% humidity, so condensation is dealt with even when nobody remembers the switch. The run-on timer scales from 5 to 15 minutes depending on how long the room was used, and an optional constant flow mode speeds the fan up against long ducts or windy conditions.For larger wet rooms on 150mm ducting, the Elta DEXA dMEV 150 is the continuous running option in the bigger size.Installation notes Mount on a wall, ceiling or window into a 99mm duct or opening. Window mounting needs a window kit. Through the wall it discharges direct to outside, from a ceiling or internal wall it is ducted. Set the installation type and the minimum and intermediate speeds on dip switch A before powering up (minimum 0 to 58 m³/h, intermediate 29 to 72 m³/h). Dip switch B enables constant flow and can disable the humidistat or timer. Wire L, N and an optional switched live (LS) for boost, for example from the light switch. Do not over tighten the PCB terminals (maximum 0.15 Nm) and fit an omnipolar isolator with at least 3mm contact separation. In a room with an open flued fuel burning appliance, make sure there is enough make up air. Ensure there is an air return path into the room, such as a door undercut. Leave it running continuously. Clean the front cover and blades periodically with the power isolated. You'll also need Window kit only needed for window mounting, ask us for the right kit.
