## Features

- Ensures longer life of fan motors.
- Not suitable for use with fans higher than 300w or fans that already have built-in fan speed control (including switched speed).
- Note-If the fan shows signs of struggling it should be dialed back up until running smoothly.

- Do not use Variispeed to turn fans OFF, switch off at mains to stop fans.

## Questions & Answers

**Q: I have a pedestal 3speed fan that is too fast even on low setting. Will this give me slower speeds.**
A: Yes I brought one for my fan that's 3 speed and slows it down

**Q: will this work on inline extractor fans**
A: hi it works on extractors , thanks chris HIGHSTREETHYDRO LOOKING FORWARD TO YOUR ORDER !

**Q: I notice on the packaging it says "up to 300W or 8" fan". The 8" isnt mentioned in the writeup , so is anyone using a bigger fan without problems?**
A: For the price it's excellent, a 300w fan is very powerful and I'd be surprised if you had one rated that much, check on the fan for the rating, it'll say something like "220-240v ac 100watts"  this controller will make some fans hum especially if your fan has multi speeds and you set it low and then use this gadget,best to set it high and use this to bring it back down,it's to do with the number of coils switched in or out for speed control.

**Q: Can this be used to reduce speed of grass trimer?**
A: This is only intended to be used on an in-line fan, we would not recommend it for use with any other item.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by B***T on 30 November 2025*

Very good product just what I needed for my inline fine, works well and easy to use.

### ⭐⭐⭐⭐⭐ Does the job! and no other competitors on the market!
*by D***S on 17 December 2025*

Used this to slow down my fan. It helped make it better for night time. Kinda cheap feeling, but does the job!

### ⭐⭐⭐⭐ Fan too fast? Here's how I slowed mine down!
*by G***R on 17 August 2025*

I honestly didn't expect much from this 'gadget' but I was surprised to discover it not only slows my regular 10" desk fan, but can also controls the speed of my (virtual hurricane) floor standing industrial 18" B&Q fan too. I rated it four star only for it's one niggly drawback. The fan needs to be switched to full power mode, else the motor will hum loudly as it's speed is progressively lowered below below 80%, the lower the speed the louder the hum, until the fan eventually stalls completely. Pro's: Does what it says on the listing. Con's: The point between too fast and dead stop can be a bit of a juggling act. Conclusion: Was it worth the money? YES! ✅
