nathand Posted August 10, 2010 Share Posted August 10, 2010 Hi guys just a quick question ive found a new place to put my coal forge now, but am in the process of getting it set up, ive located a 100mm (4inch) plastic fan that will shift approx 280m3 of air an hour ive set it up with the idea of just seeing how it will run, ( as i was given it for free)i have a bottom blast forge and am planning using coke once the fan is running the air supply seems well how can i explain it is suppose its medium at best, im just wondering if this would be man enough to get the right amount of heat, also am wondering what amount of airflow will be required in terms of extraction. I ws thinking of a plastic fan as there is a hydroponics shop near where i live and they do various sizes that are relitively cheap, like the rest of the tools i require i am finding purchasing the right equipment rather difficult so am trying to make do with what there is freely available If my post seems a bit ignorant please forgive me as im a relitively new to this thanks Nathan Quote Link to comment Share on other sites More sharing options...

John B Posted August 10, 2010 Share Posted August 10, 2010 Hi Nathan, Try what you have and see how it performs, if it doesn't work satisfactorily, you can use that one for an extractor fan. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted August 10, 2010 Share Posted August 10, 2010 none of your information gives us any indication of what kind of pressure it can shove through a stack of fuel rather than just in a free air test. In general it's easier to run a test with the forge you intend to use it for and see if it works without straining itself. Quote Link to comment Share on other sites More sharing options...
