The situation is, customer has a rather old wall mounted 12v extrtactor fan, with pullcord, humidistat and timer. Make is Johnson & Stanley "Dryflow"
Its wired through a transformer with PL, SL and N at the fan... Transformer is in the attic.
The problem is the fan runs constantly. I think the humidistat has gone on the blink. Customer has been using the 3 pole isolator switch to turn it on and off manually, but as its above the door, and she is quite short... she's been hitting the switch with a hairbrush and has broken the switch!
The customer has asked me to replace with a fan that just has a pullcord... no timer, no humidistat. (backdraft shutter if possible)
Can any 12v fan work with any make of transformer?
And if so, where can i buy one that doesn't come with a transformer?
Amazon is coming up blank and my usual wholesalers are too expensive.
Further info.
The bathroom has been remodelled since the fan was installed, and I think now it would be outside the relevant zone to be 12v, so there may be an option to fit a 230v IF the cable to the fan is 230v rated and i can get to the transformer and bypass it.
