How Coy Vacuum Airlocks WorkCoy vacuum airlocks (manual or automatic) remove O_2 from ambient conditions. Manual airlocks operate with the user turning ball valves for the gas and pump while monitoring the vacuum levels. Automatic airlocks operate with the touch of a button.Able levels of O_2 prior to transfer to/from the chamber. The airlock reaches the low O_2 level through a multiple vacuum/purge procedure. The standard factory procedure is to pull a vacuum to 20 in. of mercury, then purge back to 1 in. of Hg using an inert background gas. Another cycle is repeated with the inert gas. A third cycle is performed with the H_2 gas mix used for anaerobic work. On the third and final purge, the vacuum level is brought back to ambient with just a slight vacuum left to hold the seal. The seal is easily broken by the user when opening the door. Automatic airlocks are equipped with an advanced electronic program that allows adjustments in vacuum levels, number of cycles, calibration of pressure sensors, and programmable profiles, depending on the type of work being done in the chamber. All vacuum pumps are equipped with moisture traps to prevent excess moisture from the chamber or gas tanks from entering the pump. This helps prevent pump vane rusting, which can significantly damage the p
