Silverline 439766 6-Inch Axial Fan
Best OverallPros
- Good airflow for standard bathrooms
- Quiet operation at 35 dB
- Simple installation with included kit
Cons
- No timer or humidistat
- Plastic grille feels basic
The Silverline 439766 is the standard-bearer for the brand's bathroom fan range. With a 6-inch diameter and an airflow rating of 85 cubic metres per hour, it is well-suited for bathrooms up to around 8 square metres. Owner reviews on retail sites consistently praise its straightforward installation and the fact it moves air effectively without being noisy.
It is a basic on/off model, so you will need to wire it to a separate isolator switch or use the pull cord if supplied. The build quality is typical for the price point: functional plastic that does the job. For anyone needing a no-frills fan that works reliably, this is the pick.
Silverline 439768 4-Inch Axial Fan
Best Budget / Small RoomsPros
- Very low price point
- Extremely quiet operation
- Compact size for tight spaces
Cons
- Lower airflow limits use to small rooms
- No timer or humidity sensor
The Silverline 439768 is the smaller 4-inch sibling designed for cloakrooms, en-suites, or small bathrooms. Its 55 m³/hr airflow is adequate for rooms under 5 square metres. Owner reviews note it is very quiet, making it suitable for bedrooms or spaces where noise is a concern.
Like the 6-inch model, it is a simple on/off fan. The plastic construction feels lightweight, but it holds up well in dry conditions. It is the most affordable entry point into the Silverline range, and for the price, it handles basic ventilation needs without complaint.
Silverline 439767 6-Inch Timer Fan
Best with TimerPros
- Runs on after you leave
- Same airflow as the standard 6-inch
- Adjustable timer setting
Cons
- Slightly noisier than standard model
- Timer adjustment can be fiddly
The Silverline 439767 adds a built-in timer to the standard 6-inch fan. This is useful for bathrooms without windows, as it allows the fan to continue running for up to 20 minutes after the light is switched off, clearing residual moisture. Owner reviews appreciate this feature for preventing mould.
The timer is adjustable via a small potentiometer on the unit, though some users find it tricky to set precisely. The noise level is slightly higher than the non-timer version at 36 dB, but it is still quiet enough for most homes. It is a worthwhile upgrade for anyone who wants set-and-forget ventilation.
Silverline 439769 4-Inch Timer Fan
Best Compact TimerPros
- Timer in a compact size
- Very quiet
- Good for small en-suites
Cons
- Limited airflow for larger rooms
- Plastic grille feels cheap
The Silverline 439769 combines the compact 4-inch form factor with the timer functionality. It is ideal for small en-suite bathrooms where you want the fan to continue running after you leave. The 55 m³/hr airflow is adequate for the intended space, and the noise level remains low at 33 dB.
Owner reviews note that the timer works reliably, though the adjustment is similar to the larger model. The build quality is consistent with other Silverline fans: functional plastic. It is a niche product, but for those with a small bathroom who need a timer, it is a solid choice.
Silverline 439770 6-Inch Humidistat Fan
Best Auto Humidity ControlPros
- Automatic operation based on humidity
- Good airflow
- Helps prevent mould without manual input
Cons
- Sensor can be slow to respond
- More expensive than standard models
The Silverline 439770 is the most advanced model in the range, featuring a built-in humidistat that automatically activates the fan when humidity levels rise. This is the best choice for bathrooms prone to condensation, as it removes moisture without needing to remember to turn it on. The 85 m³/hr airflow is the same as the standard 6-inch fan.
Some owner reviews note that the humidity sensor can be a bit slow to trigger, and it is the noisiest Silverline fan at 37 dB. It also costs a bit more. However, for those who want a hands-off solution to bathroom damp, it is a worthwhile investment.
What to check before buying a Silverline bathroom extractor fan
First, measure your bathroom size. A 6-inch fan (85 m³/hr) is suitable for rooms up to 8 square metres, while a 4-inch fan (55 m³/hr) is best for smaller spaces under 5 square metres. Check the ducting route; Silverline fans work with standard 100mm or 125mm ducting. Also, consider if you need a timer or humidistat for automatic operation. Finally, ensure the fan is rated for bathroom zones; Silverline fans are typically suitable for Zone 2 or 3, meaning they should not be installed directly over a bath or shower.
Mistakes to avoid when installing a Silverline fan
A common mistake is undersizing the fan. A 4-inch fan in a large family bathroom will not clear steam effectively, leading to mould. Another error is ignoring the noise rating; while 35 dB is quiet, a fan placed near a bedroom should be the quietest model you can afford. Finally, ensure proper ducting insulation to prevent condensation in the duct itself, which can drip back into the fan.
FAQs
Are Silverline extractor fans any good?
Yes, for the price. They offer reliable performance for standard bathrooms but lack the build quality and features of premium brands like Vent-Axia or Manrose.
What size Silverline extractor fan do I need?
For bathrooms up to 5 square metres, a 4-inch (55 m³/hr) fan is fine. For larger rooms up to 8 square metres, choose a 6-inch (85 m³/hr) model.
Do Silverline fans come with a timer?
Some models do. The 439767 (6-inch) and 439769 (4-inch) have an adjustable timer. The standard 439766 and 439768 do not.
How loud is a Silverline bathroom fan?
Most models are rated between 32 dB and 37 dB, which is quiet enough for normal use. The humidistat model is the loudest at 37 dB.
Can I install a Silverline fan myself?
If you are comfortable with basic electrical wiring, yes. However, if you are not qualified, hire a licensed electrician to ensure it meets building regulations.

Silverline offers a standard 2-year warranty on their extractor fans. This covers manufacturing defects but not misuse.
