Robinair RA34888HD Heavy-Duty Recover, Recycle, Recharge Machine

The Robinair 34888HD heavy duty machine recovers, recycles, evacuates, leak-tests and recharges R-134a with 98.5% efficiency in both small and large mobile air conditioning systems. The new design features a large capacity, removable tank and a liquid pump to tackle those larger A/C systems typically found in buses. The product also is equipped with a nitrogen port which allows a technician to use nitrogen to dry and leak test the vehicle's A/C system. The machine is fully automatic and is capable of recovering, evacuating, leak testing, charging and oil drain/inject – putting A/C lubricant back into the system. The 34888HD also boasts the ability to add a printer for capturing and retaining vehicle service data.


  • Fully-Automatic Function: Program to recover, vacuum, leak test and charge without operating panel valves.
  • Automatic Oil Drain: A display reminds you to empty the graduated container to show the amount of oil to replace.
  • Oil Inject: Automatically inject oil back into the vehicle’s A/C systems.
  • Visual & Audible Alarm: Notifies the user when service is complete, or if a problem has occurred.
  • Nitrogen Port: Inject nitrogen into the vehicle's A/C system to dry or leak check the system.
