Hi All, The Ametek brushless AC blowers are the best. This type on Ebay is what you're looking for. 3 available!   They also make DC brushless blowers that are variable speed but they usually have a bit of a whine (like this ). Yes they can run on AC, the electronics inside are the DC part. Make sure that you buy the power type(AC/DC) and voltage that you need. I do have the details to utilize the variable speed on this type blower if anyone needs it.   Search Ebay for Ametek Windjammer f
