Ripley, Ontario Canada | You need a static pressure table, to find out what the static pressure is required to push air through your grain depth (it changes corn vrs beans vrs wheat) and size the fan according to cfm/bushel you want at max pressure. Likely if you are dumping hot corn you want 1 cfm/bushel which will take a fair bit of hp, and possibly a specially engineered fan wheel that will work at higher pressure. They put fans on 100+ foot silos here, so you can do it, it just may take 2x30 hp fans to get it and cost lots of $ | |
