Shop Vac for blowing lines out?

[JaySav]

I am currently searching for a good Shop Vac that can push enough air to blow my lines out for winterizing. I know some are better than others as far as Shop Vacs go so I'm looking at a few that have high CFM ratings, around 140 with 11.8 amps, the Cyclone is rated at 140 so I'm thinking if I can stay around there I should be good. I wanted to see if anyone had any suggestions on a specific model. I'm not real worried about blowing the lines because I plan on lowering the water level below the returns but the main drain line is a diff story. Any advice is appreciated, Thanks.

Most mains are rarely blown free of water, a shop vac will push the water far enough down the lines to close it.
