Greenwood Airvac CV2GIP Unity Any Room Extractor dMEV Fan

Low noise easy to fit, looks good, the air volume moved is good. Needed an always on fan for an ensuite with no window.this fan constantly running at a low speed and then boosting when the humidity rises is the ideal solution. Good controls so easy to set and very quiet during the low power running, only a little louder when boosting but that is to be expected and it’s still quiet.

Bought to replace an old fitting, Very effective with next to no noise, very sturdy , improves air quality, little bit expensive but you get what you pay for I guess

Got this to replace one that after about 6 yrs stopped working. Satisfied with produce although I think it could do with a bit more boost extraction

These fans are a different class from the old manrose ones that were installed when I moved into the flat. They are simple to install (or at least replacement of existing fan), look good and already I have noticed a decrease in dampness in my shower room. They run all the time on 'trickle speed' if you use the humidistat function. Then when you switch on the light (depending on how you have it wired) it goes to 'booster speed'. To avoid nuisance noise at night, the 'booster speed' only runs on timer if you have been in the room long enough. i.e. if you are in the room for < 5 mins then the booster speed switches off when you switch off the light. If you have the booster switched on for 5-10 mins then the fan stays on booster mode for 5 minutes after switching off. The booster speed and trickle speed can be adjusted to suit in the easy commissioning phase Note about the delivery - ordered Friday at 3 pm and was posted that evening for a Monday delivery. Excellent service.

Quite significantly cheaper than the competitors (although it went up by £10 three days after I bought it, but still cheaper by far). Whisper quiet on the lowest setting which is exactly what I wanted but with the option for a massive boost if required. Personally I installed this with ONLY a permanent live (with a fused spur for isolation), not a switch live from the light switch. What this means is that it runs permanently but using the settings I reduced this to the minimum speed for a constant trickle ventilation as it's only for a small downstairs toilet. I then activated the humidity sensor so that if for any reason it raises then it will boost up temporarily until it drops (so far it hasn't needed to). If required though it can run constantly as mine does but with the option to boost when a light switch is turned on and then with another option to run on for a while longer after it goes off. It's a solution to almost any extractor needs you'd require. Comissioning is done by simply twisting the outer cover off and using the easy to press buttons. Takes less than a minute to set up. Would recommend to anyone and would buy another for elsewhere in the house if required.
