The Manrose MF100S is a high-performance mixed flow inline extractor fan designed for efficient air extraction while maintaining minimal noise levels. Featuring a 4-inch diameter, this inline fan delivers a superior extraction rate due to its innovative twin-blade mixed flow design, which outperforms conventional extractor fans. This makes the Manrose MF100S particularly well-suited for use in bathrooms, kitchens, and other high-humidity areas, where effective moisture removal is crucial.

The Manrose MF100S 4-inch inline fan offers versatile operation with three adjustable speed settings, easily configured via dip switches during installation. This feature allows users to tailor the fan’s performance to meet specific ventilation needs, whether for light or heavy-duty applications. Its compact design, combined with a quiet operation of just 24dB(A), makes the Manrose MF100S ideal for installations where both powerful extraction and discreet operation are required.

Review by Robert Rushton - Stoke-on-Trent

No problems

Fan ordered to replace existing fan which more often than not would not run. Fitting no problem, a one for one replacement, but new fan noisier than the faulty fan

Well laid out website, very competitive prices and free shipping which arrived in good condition and within a few days.

The inline fan is SO much better at clearing moisture in our bathroom than our old extractor fan. These has so much more power and are really easy to install in your loft space

My experience with this company has been positive

I've not fitted the fan yet however i know someone who has one of these fans and it comes Highly rated. i saved over £30 by buying from electricpoint compared with a online and local screwfix shop at the time of purchase, exactly the same fan and number .
From my online order to having the fan delivered was just under 25 hours.for me that is excellent service.
