Review: I'm A Kair MultiFan In Line Fan Fan. - After a bit of a trawl through the available options, I chose this Kair MultiFan In-Line Fan to replace the unbranded one that had failed after over 15 years of service. The Kair MultiFan I chose is the 125mm version with a timer. It was a cinch to fit and wire up with different power setting choices. The fan unit itself separates from the mounting bracket and duct connections to allow easy positioning and fixing. The fan unit then slots back in between the duct housings and is secured by simple retaining clips which are held in place by small screws provided. The instructions were pretty easy to understand after got my head around them. I opted to wire it up for full power which involved reattaching the existing cable to the Neutral, Live and Switched Live terminals. A little plastic screwdriver is provided to alter the timer setting. Out of the box the fan turned off after about four minutes, a simple turn of the control adjusts the timer duration which I have now set to about eight minutes. It does the job of keeping the bathroom from steaming up far better than the previous fan had ever done and the noise level is only slightly higher and by no means unpleasant. It comes with a two-year warranty and only time will tell how long it lasts but, so far I'm very pleased with my purchase. Thank you.

### ⭐⭐⭐⭐⭐ Excellent quiet fan
*by S***N on 8 November 2025*

Super quiet and much more efficient than the old fan. Easy to fit, wiring not a problem after watching you tube video.

### ⭐⭐⭐⭐ 125mm fan with overun timer.
*by A***R on 10 June 2024*

Kiar,125mm fan with overun timer. Good fan fitted okay. Good that the fan can be removed from the mounting bracket. Electric wiring was a bit confusing. You tube came to the rescue. Basicly the L,live is not the switched live,its the constant live. LT,means live from a Light switch,,not constant live for the overun timer as I thought. So initially I had the lives the wrong way and the fan didnt run. I used the full power setting,if using the low power option then watch you tube,as you need to split the constant live,or use 4 core. So far all good.
