Manrose 100mm Standard Mixed Flow Fan

Product Information

High air flows are achieved through flexible duct. Compact overall dimensions. 3 speed fan settings, selectable at installation 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. Class II - double insulation - no earth required. Fully building code compliant. Fully BEAB approved

Genuine Manrose branded product. High quality ball bearing, long life motor, continuously rated and warranted for a minimum of 30,000 hours or 3 years 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........ Operating at a maximum of just 24dB(A) and with a compact design, MF100S is ideal for applications where installation and extraction needs to be powerful yet discreet. We're also thinking about cutting a new hole in the ceiling (Filling and patching up the old one) where we actually want it, and then common sense would tell me that it would make sense to have the fan on the nearest joists on the way to the outside - I think we would swap to the front soffit as that is the closest by some margin.Designed to produce higher working pressures for applications that require high air flows, with low relative noise. Suitable for long duct runs up to 12m. Offers vastly superior extraction to that of wall mounted axial fans. A powerful, 3-speed high quality ball bearing, long life motor can operate at low, medium and high speeds that produces no more than 24dB(A) making it one of the quietest fan available. Continuously rated and warranted for a minimum of 30,000 hours.

Controlled by remote ON/OFF light switch. The extraction rate of 245m³/hr leads the way in performance and power. The only negative I can see might be noise, in that the fan will be directly above the shower (Currently it is above the landing cupboard), BUT while the shower is on you won't hear it, and hopefully if it's way more efficient I won't need to have the timer at max for 25 minutes, perhaps 10 would do. MF100S is fully BEAB approved, building code compliant and is IPX4 rated Features of the Manrose MF100S Inline Fan Include: We've always been dissapointed with the performance, especially after he told us it was overkill, and we've put it on maximum timer and maximum speed. We have a small bathroom, big standard 1930's one, so do you think the 100T when ducted properly should be sufficient?I haven't investigated at all yet, but one thing he did fit is an isolator switch for the fan, so that will make working on it easier.

Had already had an idea to slope the ducting down and out of the house, so pleased to see that is mentioned above. 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.

With regards to joining the ducting, is duct tape sufficient, or should I be looking at some kind of adhesive for a better longer lasting fit?
