We developed a vacuum generation system composed of a reciprocatingcompressor (3 tons of refrigeration) with an inverted-function that is ready tobe hooked flexibly to a gas-tight container to create an evacuated enclosedatmosphere, without strict limitation of the size of that container. Theevacuated container (or vacuum chamber) can serve in different purposes such aseducational demonstration of the vacuum properties, extraction of perfumes fromherbal resources, and preserving food. We tested the device and found it canreach a vacuum level of 26 inches of mercury in an environment with anatmospheric pressure of 28.5 inches of mercury. We compared the performance ofour vacuum device to a rotary-vane vacuum pump of 1/4 horsepowers and foundthat the vacuum pump reaches a set test vacuum level of 25 inches of mercurybefore the compressor. We then demonstrated experimentally some features of thevacuum using the inverted compressor or the vane vacuum pump. These experimentsserve some topics in physics for school students as well as two core subjectsof mechanical engineering, namely fluid mechanics and thermodynamics.
