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 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? Class II - double insulation - no earth required. Fully building code compliant. Fully BEAB approved

We have a small bathroom, big standard 1930's one, so do you think the 100T when ducted properly should be sufficient? 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. Looking at the gap approaching the eaves, it would seem it is too narrow to take round pipe, the previous fitter just kind of stuffed the flexible pipe down there, so I think I will have to run 125mm pipe from the fan, and then annoyingly switch to a rectangular style with a convertor to enable it to get through the eaves and down to the soffit.The Manrose MF100T is a powerful inline extractor fan which is ductable up to 12m. An inline fan is installed in the loft or ceiling void above the bathroom (or kitchen etc). Ducting is attached to each end of the fan with one length going to an internal grille in the ceiling of the bathroom and the other going to a grille on the external wall, soffit or roof. The isolator switch works, which is a bonus, the electrics at the top had no water ingress or moisture inside. 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.

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. High quality ball bearing, long life motors, continuously rate and warranted for a minimum of 30,000 hours or 3 years. This particular model; the MF100S is the basic On/Off version. It can be paired with Manrose 1361 remote humidistat and Manrose 1350 speed controller. Key Features Controlled by remote ON/OFF light switch. The extraction rate of 245m³/hr leads the way in performance and power.Mixflo fans can be mounted in a variety of applications as shown and are suitable for use with either rigid or flexible ducting Rated to IPX4. Easy installation and maintenance with the fan assembly easily removed from rigid ducting installations using the specially designed construction 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.

Fan performance is generally quoted with the fan mounted in free space, with no ducting. The performance degrades rapidly as restrictions to flow are added, the worst thing being the stretchy 4” duct. Not only does it have not much area, but all those ribs create turbulence that further restricts the effective area. And the grills are often restrictive too, especially after a few years of use when the insect grills in them will be clogged up with fluff.Fitted with a high quality ball bearing motor, MF100S is continuously rated and guaranteed for a minimum of 30,000 hours or 3 years.

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

Manrose MF100S Features

Times I have been up in the loft, I can feel by weight and noise that a lot of water sits in the ducting, far from ideal.
