I'm looking for a CHEAP squirrel cage type blower. When I didn't need one it seems they were everywhere in all my surplus catalogs, now no cheap ones to be found. Wish I could give a size and CFM but I don't know exactly, it's a hit and miss operation for a home made waste oil heater. I'm guessing from seeing others that it's about 250 to 400 CFM. A little over sized so I can adjust the air sort of like a normal oil heater. I know this isn't much to go on, but maybe some of you have different surplus catalogs with blowers? Appreciate all leads.
