Air Vent 434399 Low Voltage Axial Extractor Fan & Transformer Kit (Timer Model) 100mm 4 Inch SELV 12V. Suitable for use within Zone 1

Purchased to replace a faulty fan in our bathroom. Works perfectly.

You have to use 12V systems near water, and this has run faultlessly from day one. Remember that the timer needs to be set to 20mins to make a difference. A little noisier than 240v ones of a similar price, but still pretty quiet.

This unit is unbelievable as it was such low cost I fear it would be low quality. I was very wrong, it an excellent choice. I installed two months ago and it has matched or even out performed the original installed unit. It is a good choice, I only wish it had the humidity sense as well but , it works just fine on the timer.

Good value easy to fit and quiet operation

Both the fan and the transformer were easy to install, straight forward replacement for my bathroom fan.

Cheap wee 12v fan and good wee timer/ transformer

Excellent - relatively easy to install - no oroblems so far after two months

I found the fan ok but the rear vent springs are very flimsy.
