    Hi all,

    I've been trying to find fans that don't require fusing down according to the instructions.

    Can anyone recommend any please?

    These are just replacements and I'm trying to keep the cost down for the customer so if I can avoid extra work to install fuses etc. I'd like to.

    Thanks

    Are they run off a 6A lighting circuit? I know it doesn't answer your question, but EDIT I think I misremembered - 3A fuse operates quicker than 6A MCB for overload currents - 7A would blow a 3A fuse in 0.05 seconds but would take 3600 for the 6A MCB to trip.
    However although there's no need to follow the manufacturer's instructions, life is probably easier further down the line if you don't have to explain that.

    The only time I fuse down a fan is if it’s spurred from a ring circuit. If it’s fed from a lighting circuit then it’s usually protected by a 6 amp mcb so as already said the mcb will most likely trip before the fuse ever blows

    Thanks Murdoch. Found the S&P ones, any chance you could point me in the direction of the other one as I can't seem to find it on-line.

    Thanks

    Thanks :)

    And yes, it's a pain in the posterior. It's alright saying it's only guidance, but who amongst us fancies their chances arguing the **** with someone in court? Personally, I don't, so I prefer to follow the MIs, it's just an excuse to off-load their responsibilities.

    I took this 3A issue up with icon .... needless to say they wouldn’t budge ....... 6A MCB versus 3A 1362 ..... just goes to show how little manufacturers know .. and understand

    Hi - here's one I used a while back. It's Vent Axia, but I don't think all their 100mm models have their own internal fuse like this one, which is why I took a pic .

    I thought the same from memory but after checking it doesn't seem to apply to overload current. Do manufacturers specify a 1362 fuse for overload protection eg shorted windings as well?

    Envirovent (the Silent 100 is an absolutely cracking fan, far better extraction rates than any other 100mm Axial fan I've come across)

    Envirovent are very good fans. They are another trading name for S&P. Same fans.

    It's a lead ended axial, soldered onto the PCB. Replaceable if you can wield desoldering gear :)

    Edit - But to be fair, if it fails I suspect the fans a write off.

    My fat fingers and poor eyesight would see me replacing the fan
