All refurbished units are fully tested at Ai before shipment. Comes with 3 month warranty.
The SuperVac
pumps are designed for reliable long time continuous operation, they
will take your equipment's vacuum down to 0.3 micron in minutes. Comes standard with all necessary fittings and a high capacity exhaust oil mist filter which also returns trapped pump oil back to the pump and makes the pump quieter to run.
Multi-level gas ballast is designed to allow purposefully pull a less deep and slower vacuum by opening the gas ballast, allowing dry air to go directly into the pump and diluting the vacuum pull, and it also helps keep moisture, solvent, and other contaminants from getting stuck in the pump, and instead passing through to the exhaust.
It is important to note that pumps should always be ran in a well ventilated area.
Free high capacity exhaust oil mist filter (0 value),
KF25 flexible stainless steel bellow (3.3 ft), clamps and centering rings set
