Review: Quite noisy but works fine & is dual speed. - This fan is noisier than others i've got but it works verry well & it's also a 2-speed fan that can be wired through a standard dimmer switch for a completely variable speed & it's inexpensive so good value.
Review: Brilliant value - Great little extraction fan. I bought this as my tent was getting hot in summer and thought I would get the added bonus of sucking out all the stale air inside the tent amongst my plants. Well it has worked for both those problems. The tent dropped 4 degrees in temperature and I've just finished this particular project and all the plants were visibly more healthy than usual when comparing this to without the fan. And don't be worried about noise either. It's incredibly quiet. My tent is in bedroom. The fan is on a shelf outside the tent and connected via extendable ducting. It's so quiet it doesn't affect my sleep pattern one bit. I have never been woken up by it or struggled to go to sleep while on either. Great little fan! Will buy again!!

## Questions & Answers

**Q: Would this be any good to extract vape smoke from a small enclosed outside room.**
A: Would be perfect for the job. A brilliant fan all round

**Q: Can a fan speed controller be used with this fan? Thanks J**
A: Yes i bought a separate 1 to use for the fan

**Q: Does this fan have a uk plug fitted**
A: Hi yes it has a standard Uk plug

**Q: Hi. Is the 4" and 5" the same power, tried looking at the pics but both the same and details don't say**
A: No idea ! They are normally measured in the amount of air movement/ hour, so I would say 5" would move more air / hour than a 4" !
