dimmer switch and timer fan

[sparkybird]

Is it possible to get an in line timer fan which will not 'dim' if a dimmer switch is used to control the lights?

The existing scenario is that the at the switch (dimmer) there is switch line only. JB in the loft for the permanent and switched live to fan. Client wants no damage to walls, so the only thing I can think of is to put the fan on it's own pullcord (ie not to have it linked to the lights) but it would be better if there's a fan out there which will work with the lights, but without 'dimming'. I seem to recall seeing one somewhere that had some sort of control panel, but this was a through the wall one.... and it was some years back, so can't remember make etc

Can anyone help?

Bump....

I'm assuming that it's not a good thing to have a fan on a dimmer? Can't think it does the dimmer much good or am I mistaken??

As you suggest, the dimmer and possibly the fan electronics (if it has electronics) will be damaged sooner or later.

I can only offer three suggestions:

1) change the dimmer for a switch.
2) use a contactor with a coil designed to operate at between 50 - 230 volts (I have used such contactors many years ago but do not know if they are available now)
3) Can't you get a dimmer which also incorporates a single pole switch?

Of course there are simple ways to do this with electronics but it would take time and tricky to keep it reliable and compliant with elect regs.
