Inquiry (采购产品): portable vacuum I'm assisting a local high school in the FIRST robotics competition, and I have a question. We need a suction pump strong enough to pull a 7" diameter 1/2 pound ball through a 4' long tube. It is driven by a 12 volt battery, but we'll consider other battery sources. Size is limited, of course, so it has to be small. Is there such an animal? Thanks. Tim Freriks tfreriks@telsim.com **** Hidden Message ***** Tim Freriks 10012 N.
