Extractor Fan World Review of the Turbo Tube

This fan is so good we made a film about it! Watch our Turbo Tube video review.

At 300m3/h, the Turbo Tube is the most powerful 4 inch fan available and is perfect for all domestic bathrooms. Indeed, its extraction rate 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, totally out of sight, 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 20 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.

This model features an integral over-run timer which turns the fan off after a set period, once you have switched it off. This ensures all steam and moisture is removed form the bathroom. The timer is adjustable from 3 to 25 minutes. We would always recommend the user of a timer version over a standard model.

There are quite literally hundreds of extractor fans on the market... but you needn't look any further! The Turbo Tube is the best fan we've ever tested. It beats any wall mounted axial fan hands down and is more powerful than any other inline fan.

Installing the Turbo Tube Inline Duct Fan

You will need the following, all available from the accessories list below:
1 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.
Inline Extractor Fan Installation Guide

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:

No coring through brickwork required, just a simple 4 inch hole in the ceiling that is covered by a discrete grille.
It's easy to install - in the attic, ceiling void or loft space - there are no electrics for the fan in your bathroom at all.
This means there is no making good to be done when the job is finished. No plastering, painting or re-tiling

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 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.

Powerful fan with high build quality (except the screws!)

This is a really good fan. I replaced the horrible old inline fan and ducting run that wasn't working as it was a total bodge job, and had caused a lot of mould in the bathroom that sadly had been painted over by the vendor before we purchased the house.

I found this website and fan through watching a youtube video from CharlieDIYte. The recommendation was good, as the staff were really helpful and knowledgeable on the phone when I called them up multiple times for advice pre and post installation.

The fan itself is of good build quality, the only niggle I have is the screws for the electronics enclosure are really cheap, poor quality screws the heads stripped very easily. I replaced them with some similar dimension pozi screws I had lying around, which makes for a much better enclosure seal as I can tighten the screws adequately, without fear of stripping the head.

The install itself was simple, although time consuming given the confined space and damp dark conditions in the loft. I used an existing showerlite fitting in the ceiling as the intake, and installed a new grille vent in the fascia for the exhaust. I installed an inline backdraft valve in the exhaust side of the ducting run. For the run itself, I used solid 100mm PVC pipe for the majority, as this improves airflow and reduces water pooling as there is less nooks and crannies for the steam to catch and condense on. I used a short section of flexible ducting to make the bend from vertical to horizontal. I used jubilee clips on all the joints to make sure they are good and sealed, and then I wrapped all the ducting in plenty of insulation; I used some leftover loft insulation first, fixing in place with long cable ties, and then a layer of foil bubble wrap insulation to seal it all up, again fixed with long cable ties.

The fan itself is not mounted to a joist, but on recommendation from my dad, suspended from the rafters with some used bike inner tubes. This acts as a damping system, reducing the noise and vibration of the fan. As a result, the fan is very quiet, you can only really hear the whirring noise of the blades spinning, rather than echoey mechanical noise reverberating through the house as I have experienced before.

Extraction is very powerful and I am really pleased with the product and customer service I received. Thank you Extractor Fan World!

Powerful fan

My original fan seized so I chose to upgrade to this and boy what a difference , it has 3 speed settings and I have a medium sized bathroom the fan vent is just outside the shower and I have set the fan to the fastest speed and it keeps the bathroom clear of steam when using the shower , I would recommend this product
