Vacuum pumps are part of among the final processes in the repair procedure. After you’ve diagnosed and repaired any leaks or additional issues in the machine it’s time to recharge. Before recharging you want to make sure the system is free from any undesirable gasses, air, or drinking water. If these were to stay in the system, it could turn the oil it runs on into sludge and keep behind damaging impurities.

The draw on vacuum pressure pump is usually divided into its “CFM,” or Cubic Feet per Minute. To estimate what your CFM needs, look at the tonnage of the Ac Vacuum Pump systems you work on. Take the square root of that number and you’ll obtain the approximate CFM you need to have to utilize that system. Typical residential systems need 4-5 CFM, while industrial and rooftop systems generally need as much as 6-8 CFM.
