At 300m3/h, the Turbo Tube TT100PROT is the most powerful 4 inch fan available, perfect for all domestic bathrooms. The extraction rate on on the Turbo Tube is almost three times that of the best surface mounted axial fan. It is also quiet and being installed in the loft above the bathroom, is totally hidden from view, the only visible part in the bathroom is a discrete flush mounted 4 inch circular grille.
Ducting an extractor fan to the outside world can be problematic. Indeed all wall mounted axial fans require the chopping of a four inch hole in your bathroom wall! Not so for the Turbo Tube, which is usually ducted to a convenient place in your soffit. Using 'mixed flow' technology, which combines the features of both axial and centrifugal impellers, it generates greater pressure and can thus cope with long duct runs of up to 10 metres without significant loss of power. This gives total flexibility in installation allowing you to site the fan in the optimum place for extracting, ducting, mounting and electrical connections.
It is also suitable for installations in which dust and grime can cause problems for other fans - such as commercial kitchens or workshops. The Turbo Tube, uniquely features a removable chassis - permitting easy maintenance and cleaning.
You will need the following, all available from the accessories list below:
2 x Length of flexible aluminium ducting (sold by the metre)
1 x Internal back draught shutter
4 x Duct clamps
1 x Circular internal grille
1 x Fixed external grille - available in white, grey or brown
1 x Condensation trap (If the fan and duct are fitted vertically)
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.
Duct clamps are used to connect the ducting to each end of the fan and to the spigot of each of the grilles. The back draught shutter may be installed anywhere in the exhaust ducting - that is to say, the ducting which runs from the fan to the outside grille, but is usually situated as near to the outside grille as possible. It's worth pointing out, that the backdraught shutter must be fitted the right way round!
Unlike a wall mounted fan that is installed in the bathroom; an inline fan sits out of sight, within the run of ducting in the loft or ceiling. This offers the following benefits:
The fan can be mounted anywhere along the duct run - wherever is most suitable for wiring connections and secure mounting. Ducting is then connected onto both ends of the fan, one for the input side and the other for the exhaust side, totalling your full duct run length.
To prevent air from coming back into the room via the duct run, an in-line backdraft shutter is fitted somewhere in the duct run. Either on the exhaust end of the fan, within the run of duct held in place by a duct clamp, or at the exterior grille for example.
Exit to outside requires a grille We recommend the Energy Saver No Resist Backdraft Grille - which prevents backdraughts without adding resistance to the ducting system. Internally, a grille is fitted on the ceiling. To ensure the ducting system is entirely air tight - which maximises the efficiency of the fan - we recommend the use of duct clamps when attaching the ducting to the spigots of the fan and grilles.
In summary, the Turbo Tube is not only the best inline duct fan, but in our expert opinion, it is the best all round fan available. If you have loft space above the bathroom and if your installation allows, the Turbo Tube inline fan is the best extraction solution. Also available in 'Timer' version.

Simple to do a swap over from a "builders fan". A tiny bit noisier but the extraction is really good.
This in line fan is quite an improvement on a ceiling, and quiet in use.
Great price, quick delivery and works well.
Replaced my old inline fan with this baby, great article, runs quiet in the roof space, it would suck the skin off a banana, great job. First class service from ordering to delivery
Good, a lot quieter than the last one, and delivered super quick.
The instructions could be better laid out and defined, especially the electrical connection codes. The product seems to working well. Same size as the one it replaced but at least twice as powerful.
Power of fan, real strong
Easily installed
I'm not great at DIY but needed a quick fix for an old fan that was on its last legs. Delivery was very quick and efficient. Installation was much easier than I had feared, it runs very quiet and, even on the low setting, extracts the steam from our bathroom very effectively. Does everything I had hoped.
Easy to install and runs well
Easy to install and this unit, compared to the previous manufacturer we had when the house was new, is wolds apart. You can hear the draw of air and how powerful this is. It extracts a good level of steam from the shower that i now find the the bathroom mirror is no longer fogged up after a shower. Will be looking to replace my other bathroom extractor fan later and will definitely purchase one of these units. Great price too.
Brought this as our other fan wasn't powerful enough. Arrived quickly, easy to install and works great. Nothing to dislike.
Good quality and easy installation. Keeps shower room clear of condensation. Although a little noisier than I thought it would be despite mounting on isolation pads.
Good throughput and pretty quiet. Doing ok for laser cutting extraction.
Excellent extractor fan! It's powerful, quiet, and does a great job removing steam and odors quickly. Easy to install and looks sleek once fitted. Definitely a high-quality product and great value for money, highly recommend!
Best inline fan yet.
Very effective at clearing condensation from shower room..
So impressed going to buy another one for bathroom
Good fan work well and very quiet too will buy again, good price. Good delivery.
it clears the bathroom from steam in no time at all
Bought as a replacement so very easy to install. Powerful with three speed option and timer. Great service.
Easy to fit and very efficient
This is truly an exceptional product. Very easy to fit and very quiet also. It has different speed settings and even on the highest setting it is still very quiet and very powerful. Would highly recommend this to anyone that might be thinking of an in-line filter.
Easy to fit as a replacement for an old low capacity fan. Impressive flow that clears steam from bathroom after a shower. Working great so far.
Ordered the wrong fan without the timer. Couldn't be more helpful, correct one sent on next day delivery, directed how to arrange return and refund. Brilliant service and great product.
The fan extraction rate is good but it is very noisy. I am a lifelong Electrical Engineer and quality of this product is not good. The terminal box cover and motor retaining strap screws and very bad and poor quality. The cable terminals are bad, difficult to secure flexible cores. The instructions suggest using flexible cables. DO NOT ATTEMPT TO USE SOLID CORE CABLES WHICH ARE NORMALLY USED FOR EXTRACTOR FANS. I have installed this fan in a loft above 200mm insulation on a horizontal mounting frame and the fan is mounted on foam spacers. The fan is still very noisy. Unacceptable to many people. Overall it is disappointing.
Replaced an old bathroom extractor fan with one of these. Old fan had timer so wiring was like for like. Previous fan was ceiling mounted so small amount of work was required to add extra ducting and mount this extractor in the roof, but was easy to do. This extractor is excellent, very quiet and very effective at removing damp air after showering. Definitely would recommend.
Nothing
Seems powerful and quiet
Clears en-suite of steam very quickly.
I bought to this to replace another bathroom extractor fan that had stopped working. It was easy enough to install up in the loft above the bathroom attaching to the existing air conduits. I made a cardboard template to drill the mounting screw holes in the wall, as no template or measurements were provided. I find the electrical terminals a bit close together and a bit fiddly. The instructions said it comes factory set with a 15 minute over-run. In fact it was pre-set at about three minutes, but that was easy to adjust. The fan sounds reasonably quiet alongside, but is louder in the bathroom through the air vent. It was a bit more expensive than similar models. Happy so far. Let's hope it lasts a few years.
A really well made fan, very quiet and powerful.
This fan feels like it moves a lot of air compared to our old dmev, the bathroom definitely clears quickly and smells fresher. It was easy to install and felt sturdy when I was working on it. The only reason I've marked it down as 4 stars, not 5 is because it's louder than I expected. The bumf you read about inline fans is they're quiet because they're not in the room, but the noise travels down the duct and into the room. I don't think it's louder than the dmev, but you can definitely hear it.
This in-line fan is to replace our bathroom extractor fan - so much quieter and noticeably more effective. I am very pleased with this product and would be very happy to recommend.
