Apart from a simple floor pump, you'll need some PVC hose, a check valve (that lets air in one way and not the other), and a hose clamp. Essentially, all you need to do is reverse the piston and ...

The research team led by Professors Stefan Seelecke and Paul Motzki from Saarland University will be exhibiting a prototype film-based vacuum pump at this year's Hannover Messe from 31 March to 4 ...

In 86 degree F weather, for example, your pump need only pump to 32,000 microns to begin boiling water (remove moisture from the system). In 21 degree weather, your pump must be able to reach 2,500 ...

Interestingly, the film-based vacuum pump is “able to pull a vacuum down to 300 millibars of pressure (30% of standard atmospheric pressure).” “Our technology is cost-effective to manufacture.

A: No, you don’t, but this vacuum pump certainly makes quick work of a tedious job. I was able to flush my brake system in about 35 minutes, probably a third of the time if I had used the ...

The power valve should not open until vacuum drops below that stamped on the valve (i.e., if the power valve is stamped "65", the valve should not open until vacuum falls below 6.5 inches Hg).
