Review: Silavent direct replacement - The silavent extractor fan in my daughter’s house was old and noisy. Couldn’t find silavent anywhere but this one said it was even though it had a different name on it. I can confirm it’s a direct replacement, it’s identical. So wiring and fitting it was easy. Nice and quiet. Hope it stays that way.
Review: Easy to install, good VFM, does what it says… - Really does what it says. Was a like for like replacement so dead easy to install with existing fixings, default timer setting used and it just works! Delivery was as described too.

## Questions & Answers

**Q: I have the sdf100t fan at present and wish to replace it with the sdf100tb what is the difference?**
A: Solace to do not list a sdf100t fan in their range, I suggest you ring 01903255424 , customer support.
I suspect they are the direct replacement.

**Q: Can you fit to a wall**
A: you need a hole through the wall to the outside air and you can then fit it to a wall

**Q: Does the silavent sdf100tb sdf100b 100mm 4" extractor fan standard & timer model 80 m3/hr (standard (on/off) have a pull cord?**
A: No not this model its a timer fan usually triggered by turn on the light, then when the light is turned off the fan runs on for the timed period.
The standard one can be order as a pull switch, either off or on.

**Q: I currently have a Silavent fan with a transformer can this one just replace it ?**
A: My fan was installed by a qualified electrician and operates when the bathroom light is switched on but I am unable to pass opinion regarding the enquiry. I should add that I was not aware there were Silavent fans with a transformer, ours operates off the normal household 240v supply.
