## Description

Kair MultiFan In Line Fan 100mm with Timer : desertcart.co.uk: Business, Industry & Science

Review: Good extraction for small bathroom - First up, my bathroom has never had an extractor fan and desperately needed one. I'd been running a dehumidifier after every shower. I wanted an extractor to run on a timer facility, so went about taking a permanent live feed from the pull cord to a new isolator in the airing cupboard. Switched live was taken from the light to the isolator. The screws on the Kair extractor fan cover to expose the wiring terminals were very small but with the right screwdriver a doddle to undo. Wiring was straightforward and much easier than core drilling the gable end in a tight space. What I really liked was the ability to leave the fan body wired up in the loft space but bringing the fan chassis stand assembly of it down to the landing. This gave me improved workspace and where I screwed the chassis onto a board. I also connected the 1m flexible insulated ducting and then reassembled the fan back into the chassis in the loft. The board was then screwed down into position but sitting on some rubber grommets I had from a previous job. I set the fan timer a couple of times. First setting ended up running for 20 minutes after lights out. 2nd attempt had it at 12 minutes. Bit of trial and error getting it to the time you want it to run for. Thankfully, just a quick job to adjust. Extraction from the 100mm fan is very good. The fan itself isn't noisy but the suction sound is. It'll easily hold a piece of paper to the ceiling at the inlet duct, so plenty powerful. With the bathroom door closed and from other bedrooms, I can barely hear it. It's doing exactly what I wished for and I haven't now needed the dehumidifier. This item in my opinion was a fantastic price and I'm happy with the quality and performance from it.
Review: A Great Product. - Used to replace a defunct shower extractor fan. Easy to install and much quieter than the original fan. In fact I was so impressed I bought two more and changed all the shower extractor fans. I would definitely recommend.

### ⭐⭐⭐⭐ Works well, could do with better written instruction/diagrams
*by M***. on 24 April 2025*

Unit works as expected, good amount of flow with the max speed (2 settings apparently, not tried the other). Wiring diagram useless tbh. Asked for clearer instruction and was invited to call an engineer instead. Quick google and found a YouTube video - easiest way to see how to connect. Fitting easy once wiring sorted. Operation is reasonably quiet (wall mounted to keep off the ceiling helps). Overall pleased with the product.
