Manrose 100mm Standard Mixed Flow Fan

Product Information

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. 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 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.

Class II - double insulation - no earth required. Fully building code compliant. Fully BEAB approved 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.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. High quality ball bearing, long life motors, continuously rate and warranted for a minimum of 30,000 hours or 3 years.

We have a small bathroom, big standard 1930's one, so do you think the 100T when ducted properly should be sufficient?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........

Easy installation and maintenance with the fan assembly easily removed from rigid ducting installations using the specially designed construction The Manrose 4 inch inline fanprovides a high extraction rate whilst keeping noise to a minimum. The mixed flow created by the twin blades enables the fan to pull more air than a conventional extractor fan making it ideal for use in bathrooms and other areas of high humidity. Suitable for mounting in lofts or ceiling voids and for use in applications such as bathrooms, shower rooms, kitchens and more

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. This particular model; the MF100T, features an over-run timer that keeps the fan running for a period of up to 20 minutes (set upon installation), after power off, to ensure all moisture or stale air is extracted. watts power consumption (low / mid / high speeds). 50 / 60 / 68 litres per second / 180 / 216 / 245 cubic metres per hour extraction rate (low / mid / high speeds)
