I've just replaced my 100mm bathroom extractor fan with a more powerful 150mm fan. I'm using two reducers (150mm to 125mm then 125mm to 100mm and then onto the 100mm ducting). I then have a cowled vent cover on the outside which fits to the 100mm ducting. The fan is fitted to the wall of the bathroom, not through the ceiling.
After having my shower this morning I noticed a fair amount of condensation building up and dripping from the casing of the fan. Is the reduction of 150mm to 100mm restricting the performance of the fan and the damp air that it can't remove is condensing on the plastic instead ?
Thanks, Lee.
