| 464388 | 2006-06-24 20:49:00 | May I make an alternate suggestion Instead of worrying about a 12volt supply and all the complications, why not get 1 - 4 Microwave cooling fans No idea of airflow, but its has to be high to get rid or 600 - 900 watts of heat About 50% of the output of a MW is heat so if it take nominally say 1400 watts, then the fan is pumping 700 roughly. Most of these are about 150 mm in Dia driven by a small induction motor but some old ones had small centrifigal fans. Probably have one or two Any service company has bundles of dead microwaves around. I dump more than I care to think about and have ceased saving fans. I have a box full and can send a number of similar (but not necessarily the same) for the cost of the freight 2nd suggestion, at the top of Queen street in Auckland is a company called Surplustronics and the last time I called in there, they had very large cased fans from mainframes Like the normal 80 mm computer fans but way bigger Many are 110 volt AC but 2 identical ones in series would work well. Hope this helps Tony |

| 464389 | 2006-06-24 23:19:00 | This is what I'm looking for, . grainger . com/Grainger/wwg/productIndex . shtml" target="_blank">www . grainger . com Can you get these things here? Graingers only sells to companies and even excludes the automotive repair trades . I used to purchase for a hospitol in Los Angeles, and had an ID with Graingers to buy at any of their outlets . You need to be a registered purchaser, but I don't see any reason why they won't ship to NZ . I have shipped for people in South America a few times (Argentina & Brazil) . Just make sure you are not a non-profit company . . . they draw another line there too . There are other sources though . Let me check a few tonight for you . |

| 464392 | 2006-06-25 03:40:00 | Im after real cheap options - that graingers one is over $100 USD, and shipping would be at least another $50 . I dont think a microwave fan would work - if it was blowing out that much air you would know about it -180L per second of air is quite a bit . I'll give the aircon people a bell, I just want an old crappy fan, perhaps they will have something for me . My friend suggested one of the blowers out of an old hand dryer like you find in public toilets, I'm not sure if that would be enough flow . |
