Hey everyone. I have a releaser and am now looking for a vacuum pump. I have about 250 taps and don't want to spend the money on large scale pumps. I am looking in to some of the Robinair pumps. Has anyone tried any of the pumps I linked to. My only fear is that they might over heat. I believe they are rotary vane pumps
