Manrose 100mm Standard Mixed Flow Fan

Product Information

MF100S benefits from 3 speed settings which can be set via dip-switch at installation. This allows the fan to operate at an appropriate rate for user requirements. The isolator switch works, which is a bonus, the electrics at the top had no water ingress or moisture inside. Total distance should be radically reduced anyway, and there should be no turns apart from necessary ones, into the fan and out of the house, although I am thinking to mitigate at least the one out of the house by just using a 45 degree elbow, and then cutting the pipe going out at an angle to give a flat exit if that makes sense. Mixflo fans can be mounted in a variety of applications as shown and are suitable for use with either rigid or flexible ducting

And re-visiting my mention of the bigger more beefy fans, would it be wise/sensible to go for 150mm ducting and then use a reducer if I can resurrect the current 100T.

He put the vent in the middle of the bathroom, instead of above the shower, and has placed the fan a decent distance away from the actual vent hole in the ceiling, and then ducted to the side of the house - he's also used (to much) flexible ducting........ We have a small bathroom, big standard 1930's one, so do you think the 100T when ducted properly should be sufficient? I would say that a fan rated somewhere around 200m3 per hour is probably sufficient provided it’s installed in a way that means it can get somewhere close to that in use. The easiest way to achieve that is to make the ducts and grills bigger. But don’t go too large as then the air speed will be very low and this could lead to condensation on “dead spots” for example on bends. Over the years I’ve always used 4” fans personally and never had a problem with excessive condensation or steam (except when something needs cleaning or clearing) despite the lengthy showers the family seem to like.

Easy installation and maintenance with the fan assembly easily removed from rigid ducting installations using the specially designed construction. I'm also wondering if I should try and insulate it from the joists somehow, maybe mount a piece of wood on some foam that goes onto the joists, and then mount the fan onto the piece of wood that bridges between them?
