Robinair BOSCH RA34988NI Premium Refrigerant Recover, Recycle, Recharge Machine

The new Robinair 34988NI Premium A/C Machine combines ease of use and superior accuracy. It recovers, recycles, evacuates, leak tests and recharges R-134a vehicle systems quickly and accurately. The fully automatic function will recover, vacuum, leak test and charge on its own without the need to stand and monitor the machine. The product is fully SAE J2788 compliant and exceeds the requirements for charge accuracy and recovery efficiency. Robinair's patented automatic refrigerant refill feature maintains a user-selectable amount of refrigerant in the internal vessel and signals when it’s time to change supply tank, no monitoring required.

The 34988NI will automatically add oil if necessary using load cells that measure the amount of oil removed from the system and automatically putting the right amount of A/C lubricant back into the system, make the 34988NI the only true fully automatic machine available today. The new 34988NI now comes with two separate oil inject bottles so two different types of oil can be stored and injected making it easy and convenient as technicians service different vehicles. A large, easy-to-read color display and a printer are standard upgrades on the new 34988NI. It also has the capability to inject UV dye into the vehicle's A/C system for leak detection and making any future maintenance easier. An optional refrigerant charge and oil capacities database is available for North American market vehicles which saves time from having to look up unknown charge amounts.


  • Fully automatic operation frees technician to perform other tasks while servicing the vehicle's A/C system.
  • Automatic oil drain and inject feature enables the machine to measure amount of oil removed from the vehicle and automatically puts the same amount back in free the user from measuring the amount of oil removed.

  • Large, easy-to-read graphical display.
  • Standard onboard printer gives the user the ability to print service data to present to a customer after service.
  • Unique Automatic Refrigerant Refill maintains a user-selectable amount of refrigerant in an internal vessel and signals when it’s time to change supply tank, no monitoring required.
  • Programmable vacuum feature defaults to 15 mins, but allows the user to select desired vacuum time up to 99 minutes.
  • Automatic Air Purge eliminates system-damaging air without monitoring gauges or opening valves.
  • Save before and after service data allows the user to store before and after service information by vehicle.
  • Visual and audible alarm notifies the user when service is complete, or if a problem has occurred.
  • Automatic Dye Inject gives the user the ability to use the machine to inject UV dye into a vehicle’s A/C system.
