I have a 75 L Autofridge, its about 10 years old & still works well however the fan has given up the ghost. The connections on the fan corroded out, I resoldered them about a year ago but they are beyond repair now. The original fan is a sunon & its rated at 2.8W, I have found some cheapies on Ebay for $4 or $6 but they dont give the wattage. They do say they are .25A. would these be suitable?

Not an expert by any stroke of the imagination, but seem to remember P=VxI
which working on 12.8v would work out to 3.2watts, I would have thought this would be ok.

But I stand to be corrected

It sound like a standard off the rack muffin fan.

Almost any fan the same size will work, although I do like the sunon fans

Altronics stock Sunon as do some other electronics suppiers.
Jaycar stock their own brand and they are respectable, but not as nice as the sunon.
Even the local computer shop may have somthing that will do the job.

Just be carefull, there are a couple of different speeds arround, lots of those used in the computer business have reduced speed compared to the industrial product...this reduces the noise, the airflow and the current drawn.
If its an industrial product it will spin at arround 2800 3000rpm, the computer items may spin at 2000 or 1500rpm.

Lots of the modern fans will be more efficient than the older items, so they may draw less and shift the same air.


I'd strogly recommend a magnetic levitation fan as there are no actual bearings, they are quieter and run longer.

How big is this fan?

cheers

HI 337

Look up Autofridge on the web and you will see the address last time i looked it was in Botany in Sydney
I am sure he still makes the Autofridge
I have had a 40 litre Autofridge for about 10 Years
I took it there and had it modified
