Vacuum pumps are component of among the final procedures in the repair procedure. After you’ve diagnosed and repaired any leaks or various other issues in the system it is time to recharge. Before recharging you need to make sure the system is free from any undesired gasses, air, or drinking water. If they were to remain in the system, it would turn the oil it runs on into sludge and leave behind damaging impurities.

The draw on a vacuum pump is usually divided into its “CFM,” or Cubic Feet per Minute. To estimate what your CFM requirements, consider the tonnage of the Ac Vacuum Pump systems you work on. Take the square root of that amount and you’ll get the approximate CFM you must have to work with that system. Typical home systems need 4-5 CFM, while commercial and rooftop systems generally require as much as 6-8 CFM.
