Bathroom Fans

Best option: Inline ceiling fan
• Placed above your bathroom in the ceiling void if installation allows
• Can duct from anywhere on the ceiling including directly above the shower unit
• No electrics in the bathroom as fan housed in ceiling void
• Discreet ceiling grille for aesthetic installation
• We recommend the Turbo Tube Pro range:


Second best option: Wall mounted fan
• Ducts straight to the outside through an external wall.
• Can be ceiling mounted but can only duct up to 5m in a straight line.
• We recommend the Silent Tornado range which can be placed in any bathroom zone:


• Basic model - can be installed to turn on and off with your light switch
• Timer model - continues to run for a pre-set amount of time after light is switched off
• Humidistat model - automatically switches on and off dependent on the humidity in the room

Any 4" fan will replace another 4" fan in terms of size, however some fans have secondary functions which may require additional wiring, so you must replace exactly if you wish to use the existing wiring.

If Your Existing Fan...

1. Turns off with the lights or remote switch immediately - Then you have a ‘Basic’ fan. Replace with the Tornado ST100B
2. Continues running for a certain period after switching it off - Then you have a ‘Timer’ fan. Replace with the Tornado ST100T
3. Turns on when there is steam in the room - Then you have a ‘Humidistat’ fan. Replace with the Tornado ST100HT
4. Turns on when you enter the room - Then you have a ‘PIR (occupancy sensor)’ fan. Replace with the Tornado ST100PIR

The shutter should be positioned horizontally in the ducting so that when the fan is off the shutter closes due to gravity. It also needs to be placed as close as possible to the exhaust end of the fan so that the expelled air is able to force the shutter open.

Integrated fans with showerlights allow you to install a unit with minimal wiring as the light and fan are already internally wired. However, the fan units are smaller and therefore less powerful, equating to lesser extraction performance and shorter ducting runs.

In contrast, adding a shower light grille to an inline fan retains all the extraction power and ducting distance associated with inline fans. Installation requires the light grille to be wired independantly of the fan but will still be triggered at the same time as the fan. This has the added bonus of allowing you to replace or upgrade either part independantly rather than needing to replace the whole installation.

Installation Enquiries

Yes you can, but you must have the old step-down transformer removed from the circuit.

It is worth noting also, that if you are replacing a 12v fan with another 12v fan it is advised that you replace the old transformer with the one that comes with the newly supplied fan.

Occasionally installations like to throw challenges at you, such as having a thin wall to duct out of that will leave most standard fans poking through the other side when mounted.
Don't worry – here are some options that either have a spigot shorter than 100mm or can be easily adapted to fit thinner walls.

For bathroom (4”/100mm)
Airflow QT100 range
Vent Axia Svara
For kitchen (6”/150mm)
Vent Axia VA140 range

Whether you are installing a new fan or replacing an old unit we always advise you use a fully qualified professional electrician registered to one the UK's five trade bodies:
NICEIC, NAPIT, ECA, ELECSA, JIB.

Warranties for all electrical items will be invalidated and we cannot accept the return of any item deemed faulty unless it has been installed by a fully qualified professional electrician.

We cannot process any refund or replacement for a faulty item without this information.

Many fans use a light weight clear plastic membrane as an effective internal backdraft shutter. This will be blown open when the fan is switched on and shut if a draft should enter from outside when the fan is off.

Please note: when unpackaging your unit, please do not remove this part as it is integral to the function of the unit and is not packaging.

Humidistat fans will automatically turn on when they detect a rise in moisture content in the room. This can happen when the temperature falls as humidity will rise. This means in colder months or overnight these fans can switch on automatically to protect your room from damp. It is also important to note that when a humidistat fan unit is first installed it can run continuously for a few days as it settles into the new environment.

0345 683 0501
enquiries@extractorfanworld.co.uk

It is important when installing your fan that you are aware of any vertical runs of ducting as this can lead to condensation running back into the fan unit. This can be easily combatted with two methods: You can minimise any duct runs that are not horizontal and have the ducting run at a downwards angle towards the external extraction point away from the fan unit, or you can fit a condensation trap at the bottom of a vertical run to collect and disperse any condensate.

Condensation happens when the warm humid air comes into contact with a cold surface or atmosphere. It is important to note that if your bathroom is cold, you are still likely to get some condensation.

Regrettably, we cannot diagnose potential faults over the phone. If you are certain that the electrical circuit is sound and that the fan was installed by a fully qualified electrician we kindly ask that you first contact the manufacturer’s technical department directly, (all manufacturer numbers appear below), who will talk you through some common issues

If the manufacturer confirms that you do indeed have a faulty unit we will exchange or refund the item immediately.
Please follow our returns procedure here stating a very brief description of the fault and the name of the technician who confirmed it.

If your humidistat fan is mis-behaving: this can happen during sudden changes in weather and after it is first installed while it settles into its new environment. The unit should return to normal operation presently.
