Manrose 100mm Standard Mixed Flow Fan

Bought this to replace a budget fan that had finally given up the ghost after 8 years service. I ended up having to mount the last fan on rubber grommets as the vibration through the ceiling joists (which the fan was screwed to) was making a very noticeable droning noise through the bathroom ceiling. Retro-fitting the rubber grommets largely cured this but the noise was still there.... Even when the fan was on during showering the bathroom still steamed up badly (resembled a steam room!) and the fan had to be left on for 15mins after the event to clear the fog! Fast forward to the present and the Manrose fan arrived in a big box! I was amazed as to just how much larger it was compared to the fan it was replacing! Not a big deal for me as the fan was going into the loft and the area where it was to be fitted had plenty of free space. Folk that are mounting this in a very tight space I would advise to carefully check the fan's dimensions to avoid disappointment... The fan was a doddle to fit! From looking out the ladders from my garage to switching the fan on took 35mins tops, and that was me taking my time. The fan cover hiding the electrical connections is held on with 4 Philips screws and after that all you really need is a small flat blade driver for the electrical terminals on the fan block connector. Oh and you have to pierce the rubber "grommet" to thread the mains cable through to the terminal block connector and there is a cable clamp to tighten once the wiring is completed. No earth wiring is needed as the unit is double-insulated. As this is the non-timer version of the fan, only two wires need connected at the fan. Simplicity itself! The fan has two speed settings that can be used, and you select the speed by deciding which terminal you connect the neutral wire to - again very straightforward (supplied instructions quite clear). I selected the slower speed as I only have a small bathroom. I decided to re-use the rubber grommets as I had them to hand and lightly screwed the fan down onto the joist (you need your own screws for this) taking care not to over-compress the grommets. The flexible hosing was quickly connected to the fan and I used duct tape to ensure the hosing would not come loose and also to ensure an air-tight seal. You can also use cable ties (or I expect a very large metal hose clip) to do the same thing. So job done, then! What's it like in use? To be honest it's a revelation in comparison to what went before! The bathroom hardly steams up at all now, and less than 5 mins later what little steam was there is gone! The bathroom mirror is quite close to the shower (it's a bath shower with a curtain, not a shower cubicle so steam can escape beyond the shower area) but the mirror is only JUST starting to fog-up after a 10 min shower, and that disappears quickly. Noise-wise the motor itself is completely silent, with not even the faintest vibration coming through the ceiling! The noise you do hear is of the air being sucked through the vent - which you never heard with the old fan - probably because it didn't shift nearly as much air. The suction noise is pretty noticeable, but I don't find it annoying - if anything its good to know the extraction is so effective! All in all I rate this fan really highly. It seems very well made, is mechanically near-silent, shifts a heck of a lot of air (even on low setting) and is easy to install. Servicing the motor (e.g. to remove lint/dust) only involves removing two screws and the fan part of the assembly detaches from the rest of the fan body, leaving the hoses undisturbed. Excellent! Can't comment on reliability, but the fan runs on good bearings and the chassis seems solid, so I expect it'll last.

There are reviews for the similar model that has the timer function included, but to be honest, this fan is very efficient, so unless your bathroom gets VERY steamy, you wouldn't really need it. I had another smaller inefficient Manrose extractor fan fitted in the loft, when the bathroom was refitted 3 years ago. That one, Manrose Shower Light Extractor Fan Kit chrome or white was fitted by an electrician at the time, but it wasn't up to the job & was rather noisy for such a little fan. It wasn't very durable either, packing up after only two years. So decided to invest in this one. Its considerably more powerful, robust in construction & without the timer function, easier to wire up, just two wires in my case!. First thing that struck me, when I removed it out the box, was just how big it is! Compared the original (which was basically a 4" fan/motor, with simple couling around it, and a small box-cum-mounting bracket, containing the timer electronics.) This one is still a 4" fan, but the extra couling around it, means that it is approximately 10" long, 7" high & 6" across! I fitted the mounting bracket to a piece of loft boarding & screwed that to the roof joists, but I recommend that you put a piece of rubber matting or similar, between the mounting bracket and boarding, to help reduce vibrations through the roofing joists. My one is situated directly above shower itself (in the loft), so I did this to reduce noise. Took me all of an hour to fit it, its very straightforward and simple to do, but if you're not compentant with electrical wiring, best get someone in to do this, but it'll only take a few minutes to do. One handy additional feature on this model, is that it is possible to wire it for two speeds, if perferred. I chose to wired it for the lower speed, as believe me, in a modest sized bathroom, it is more than suffient! First time I used it, absolutely no steam formed in the bathroom at all! But I would recommend that you have a window slightly ajar, to allow fresh air to vent the room. This allows the fan to do its job properly, but does create a slight draught doing so! I found the room to be slightly colder after stepping out of the shower, than before with the original fan. It'll be interesting to see what it'll like in the winter! Easy to gain access to the working parts to clean, there is two arched brackets that loop over the fan assembly part, simply unscrew two screws, flip the brackets over & lift the fan assembly out. The brilliant thing here is, there is no need to undo the ducting, as the ducting is attached to two coulings couplings, that sit either side of the fan. Simple, logical & practical design sense! I also found this one to be quieter in operation than the original fan. All in all, I'm impressed with this one, it feels like it will last, but unable to comment on durability as of yet, I've only just fitted it today! Hopefully this one will last considerably longer than the wimpy fan that I had before! UPDATE: 02/05/14: I have now had this fan fitted for just over a year, and have had absolutely no problems with it at all, does the job! I used to have a small problem with mould forming in my bathroom from time to time prior to fitting this fan, not had any mould form in the bathroom since! Very impressed with this! UPDATE: 07/09/15: 2 & half years have passed now, Fan still functioning perfectly fine, still no mould forming in my bathroom! UPDATE: 08/09/16: Still good folks, no problems at all, went to clean the fan assembly a couple of weeks ago, which I've not done since I installed it 3 & half years ago, hardly any dirt to speak of, just a quick wipe of the fan blades was all that was required! UPDATE: 12/09/17: Now getting on for 4 1/2 years since I've fitted this fan.....still going strong folks...no problems at all...superb fan! (That almost sounded like I want it to break down, dunnit!!!!) :-) UPDATE: 17/01/20: It's still going! :) UPDATE: 28/07/22: Yep..it's still going. 9 years now, no problems at all. :) UPDATE: 19/03/24: It's still going! And I've never cleaned it in all that time! UPDATE: 23/08/25: Still going, & I still haven't cleaned it!

After discovering that the electrician who fitted my previous shower fan had actually used a cheap, plasticky one I trawled the web for something better and found this at a good price on Amazon. The person who fitted this one commented on how well made and sturdy it was. To be honest if I put this next to the one that came out the other one looks like a cheap toy. You need to check the measurements because for a 4" fan it is big. But it is very easy to fit and put into place. The only downside is that it is loud-sh. Mine is wired to come on as soon as the bathroom light is switched on and it goes off immediately too with no over-run. I believe if you fit an additional part you can adjust the over-run time. In terms of its ability to work well and remove steam I am very happy with it. (This fan only extracts from directly above the shower in a proper shower cubicle and is not installed in the main bathroom). I will see how it goes but in the 3 or 4 weeks I've had it installed it is working very well.

I purchased mine to ventilate a basement and reduce the humidity, and it works very well indeed, being quiet, powerful and reliable. Despite the listing info this is in fact a three speed fan! Here are the specs: High Speed - 2400 RPM, 25 Watts, 245 m3/hr, 24dB(A) @3m, Max pressure 200Pa Medium Speed - 2100 RPM, 23Watts, 216 m3/hr, 22dB(A) @3m, Max pressure 170Pa Low Speed - 1700 RPM, 20Watts, 180 m3/hr, 20dB(A) @3m, Max pressure 120Pa Fan speed can be infinitely controlled using a separate, optional speed controller Physical Dimensions: Total length, end-to-end: 298mm including the 30mm long spigots Diameter of spigots: 102mm external, 98mm internal Height O/A: 230mm (195 main body + 35mm electrics box) Width O/A: 175mm In-line fans are far quieter and a lot more efficient than their surface mounted cousins, and I chose the Manrose for a number of reasons. Chief among them is that I have Manrose products installed elsewhere and all have been completely reliable. Unlike most extractors nowadays this one is manufactured here in the UK, in Reading. So if there was ever a problem, I needed a spare part, or some technical advice, it's easily obtainable. The same is not true of imported goods. It's also very well designed, and after installation the central motor unit can be unclipped and lifted away from the mounting without needing to undo your ducting either side, which is a great feature for easy maintenance! The listing says it's a two speed unit, but that is no longer correct, and this model has since been upgraded to three speed options, selectable by altering a jumper lead under the screw down electrics box on the top. As you'll see from the specs I gave, it's unusually quiet at 24db on high speed. Wikipedia quotes 30db as being an average whisper! When powered up unconnected it's noisier, due to undirected airflow noise, but once installed it's very quiet. I have mine connected up using acoustic damping flexible duct which pretty much eliminates motor noise both at the air inlet and outside vent. It works in a roughly similar way to a silencer on a gun, and I recommend it highly. Finally, here's an installation tip for you: extractor fans are always more efficient sucking air through a pipe rather than trying to blow it down. So in other words, mount your inline extractor as close to the exhaust vent as possible for maximum efficiency and performance. But it you want some attenuation of motor noise, do use a suppressor or short length of acoustic duct between the outflow spigot and the outside vent. I hope this review has been useful to you, and as ever I'm happy to answer questions if have any - just hit the comments button below and I'll get back to you. :-)

Very powerful fan, with clear installation instructions. All working well

Like many, I had one of those silly lumpy extractor fans (Vent-Axia Luminair) above the shower, purchased at an extortionate price and just lasting two years. Annoyed and disappointed when it failed, I decided that I would no longer spend over a hundred pounds for another useless piece of Chinese-made junk - even if the company did have a "By-Appointment" Royal crest. I had not heard of Manrose and noticed the company were selling a wide range of fans and accessories - online and at the high street shops - all with with good reviews and at very reasonable prices. I had expected this fan to come with some accessories/fittings but it does not. You get just the fan and nothing else! As most people would be replacing an existing fan that probably does not matter. I already had in place most bits. Having thrown away the main part of my Vent-Axia Luminair I kept the ducting and of course the light and grill above the shower, purchased a meter of extra ducting and re-used some two-core cabling wire and set about fitting the new fan. Being a larger beast I thought it could end up sounding like a jet engine and that I'd be using the "lower" power setting. However, it turns out that this "Made in Britain" (as per labelling on box) fan is very quiet (less noisy than the Vent-Axia junk it replaced). I had also anticipated vibration from the motor from the attic. I placed a small chipboard on several plastic electrical grommets (the kind used in electrical boxes behind switches, sockets, etc) which I purchased from Screwfix for a couple of pounds and screwed it down. I also placed same grommets as dampers below the fan before screwing on to said board for extra damping. Of course now I don't believe any of that was needed. You need to judge noise/vibration for yourself and your own environment. Once I switched on - at full speed - I could hardly feel any vibration from the housing. It may look rather large but the motor is only 28 Watts. So at less than half the price of a Vent-Axia and three times the functionality (and hopefully longevity) you'd be crazy not to buy this.

Great fan. Easy to install with a clever system that allows each part to be installed in sections, did it myself and a very average DIYer. Very quiet. Pleased with it.

***Update October 2021*** The fan became to make a very weird noise. It sounded like the fan had broke and pieces of it were grinding on the housing inside. I immediately reached out to the manufacturer and described the issue. They wanted evidence of the fault and a copy of the serial number. I explained it to them that it was placed in a very awkward location sending them videos and pictures of the location. The videos had audio that showed the problem. The manufacturer promptly send a new device free of charge. I could immediately tell that they had updated the fan blade material to be more sturdy and robust. I replaced the device and emailed back pictures of the old one. Very happy with the after care of the manufacturer. *** Original review *** I bought this to replace a faulty shower fan. I had to install mine on top of a box room inside a very tight space and on the ceiling (fastened on wood). The device works as advertised and is quiet and powerful. Installation was not easy mostly because of the awkward position and partially because of the bulk of the device and that it was designed to be installed on floor (face up). One tiny quirk, I wish the lips of the outlet/inlet had a bit of resistance/texture to fasten easier the duct pipe. I used zip fasteners and easily could slip. I didn't want to use tape but perhaps I should.

Facile da istallare , è silenziosissimo . ottimo acquisto Suggerirei le istruzioni in italiano e un cavetto .... Io ne ho acquistati 2 per un impianto di aerazione , ho ottenuto un ottimo risultato .

Nachdem mein WC-Abluftventilator defekt wurde bestellte ich einen Manrose Diagonal-Ventilator 100mm. Das Gerät kam in der versprochenen Zeit. Die Montage war durch den übersichtlichen Aufbau des Gerätes mit dem passenden Rohranschlüssen einfach. Empfundene Lautstärke der Leistung entsprechent eher leise. Würde bei Bedarf nochmals kaufen.

Très bon ventilateur.

Actually it is very noisy, even at the lowest speed. Blows a nice amount of air though. Also when this is on, all digital communication over the powerline stops working. This needs some filter.

va bene
