Vacuum pumps are component of one of the final processes in the repair process. After you’ve diagnosed and repaired any leaks or additional Ac Vacuum Pump issues in the machine it is time to recharge. Before recharging you really want to make sure the machine is free from any unwanted gasses, air, or water. If they were to remain in the system, it would turn the oil it operates on into sludge and keep behind damaging impurities.
The draw on vacuum pressure pump is usually broken down into its “CFM,” or Cubic Feet per Minute. To estimate what your CFM requirements, look at the tonnage of the systems you focus on. Take the square root of that quantity and you’ll get the approximate CFM you need to have to utilize that system. Typical home systems need 4-5 CFM, while industrial and rooftop systems generally need as much as 6-8 CFM.
