Manrose 100mm Standard Mixed Flow Fan

Product Information

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. That's how it stands currently, the red pairs of lines are the current ducting - he decided to duct to the side of the house, I am proposing switching to the front, but joists might make it as sensible to go to the same side.

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. Controlled by remote ON/OFF light switch. The extraction rate of 245m³/hr leads the way in performance and power.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.

Had already had an idea to slope the ducting down and out of the house, so pleased to see that is mentioned above.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. 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 - Fan assembly easily removed from rigid ducting installations using specially designed construction

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. 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 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? 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. Easy installation and maintenance with the fan assembly easily removed from rigid ducting installations using the specially designed construction.
