We love talking to our customers. However, a brief look at the following FAQs may save you a phone call as they answer 90% of the queries we receive. 


Have a little look at them and if your question is not here, of course please contact us.


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 recomment the Silent Tornado range which can be placed in any bathroom zone:


• Basic model - turned 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

Through the ceiling with an in-line fan you will need:

• Flexible ducting (length required )

• Internal ceiling grille

• External grille

• In-line backdraft shutter

• 6x duct clamps

Extractor fan through external wall you will need:

• External grille

• Flexible ducting (length required)

• 2x duct clamps

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

• Solid ducting from the fan unit (length required)
• Solid duct connectors (no. required)
• Vertical roof kit for either a flat or angled roof
• Condensation trap

Kitchens require a 6"/150mm fan in order to meet building regulations. Please see our range here

Availability is stated under the ‘Add To Basket Button’

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.

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.

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)
Silent Tornado range
Vent Axia Svara
For kitchen (6”/150mm)
Vent Axia VA140 range

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.

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.
