I did once basically explode a squirrel cage blower with the
pressure side of a vacuum cleaner. It ran so fast that the fins
expanded and touched the housing and became a bent-up
mess before flying out of the housing across the room.
I was not expecting that.

Just one of those things you have to learn the hard way.
