The product does not include vacuum pump oil, thank youDifference between four high-pressure pumps:2. The hardcover version is more efficient than the Lite version. There is 1 more low-pressure gas storage chamber. A cyclone is integrated on the gas storage chamber, which can effectively prevent and reduce the transmission of oil to the high pressure cylinder. There is also a safety valve to better protect the machine. There is also a copper sintered filter element and a blowdown valve in the gas storage chamber3, automatic shutdown models, when the machine reaches 30mpa, it will automatically stop working. (Cannot adjust pressure)4, set pressure models, you can set the shutdown pressure arbitrarily, when the pressure reaches the set value, the machine will automatically stop.
