Xpelair LV100T Low Voltage Extractor Fan with Timer, 12V

Xpelair's LV100T is a 12-volt safety extra low voltage (SELV) extractor fan for a bathroom or toilet, sold with a remote SELV transformer, a timer and a universal mounting kit. It takes the number 10 slot in our guide to 100mm bathroom extractor fans, and it is the one on that list that gives you no airflow figure and no noise figure to argue about: the specifications carry 12 volts, 13 watts, a 2-20 minute timer and the dimensions, but nothing measured in m3/h and nothing measured in dB. On a list where those two columns are the whole conversation, that is the first thing to know before you look at the price.

The headline rating is 4.6 out of 5 from 129 reviews. The star breakdown behind it adds up to 100 ratings rather than 129 - 79 five-star, 13 four-star and eight at three stars or below - and those 100 average out at roughly 4.6, so the two figures agree with each other. The timer is triggered by a remote switch, for example the lighting circuit, and runs for anything from 2 to 20 minutes; the unit is listed as white and as 2.08 kg, and the mount can be wall or window. Everything on this page is taken from the Amazon listing for the LV100T. We have not measured airflow, noise or power draw ourselves.
