Windowless Bathroom - Ventilation Solution

Anonymous user 09/03/2024 - 3.26 PM

I have a bathroom that has no external windows. The room is surrounded by bedroom, kitchen, lounge and hallway. A ground floor flat with no access to loft. The current wall axial fan (4 inch Silent Tornado), does an OK job but still not good enough. The fan is connected to a duct which is boxed in to the kitchen and approximately 2.5m long, straight run to the outside. Due to the current box I can't upgrade to 6 inch as the current boxed duct run in on top of the kitchen cabinets. When I replace the bathroom I want to increase the ventilation. I am looking at solutions. Looking at inline, one of which is Manrose MF100T, but all instructions state that it should be a ceiling extraction, with the fan in the loft. The other is Blauberg Iso-Mix In Line Acoustic Low Noise Silent Mixed Flow Extractor Fan, which states it is suitable for both wall and ceiling so seems suitable. Other than access to the fan being in the duct (electrics) and replacement. Is there a reason why I cannot use the Manrose (or other) inline as a wall extraction rather than ceiling through a loft? I would also assume that if I am extracting steam/air, without any incoming replacement air from the outside, I may get other issues?
