Meets new refrigerant recovery standards J-2788 for high voltage compressors!
As the number of hybrid vehicles continues to increase, it present new challenges to service facilities providing A/C service work to both vehicles with traditional A/C systems, and the high voltage electric compressor systems used on many hybrids. Specifically designed to service the A/C system of a hybrid vehicle that uses a high voltage electric compressor which uses POE lubricant oil. It can be used to service standard A/C systems that use a PAG lubricant oil as well by utilizing the on board hose flush feature that minimizes oil cross contamination.

NEW Features and Functions:

  • A/C System Flush: Flushes a vehicle’s A/C system with refrigerant eliminating any residual oil or other liquid. (Flushing adapters - not included)
  • Save & Print before and after service data: Allows the user to store before and after service information by vehicle and print this information to provide to a customer.
  • Automatic Function: With this new option, you can program the unit to recover, vacuum, leak test, charge, and then walk away without having to operate panel valves.
  • Vacuum Leak Test: Will monitor the vacuum level after an evacuation, and inform the technician of a possible leak in the vehicle’s A/C system.
  • Automatic Refrigerant Refill: With this latest advance, you never have to stop in the middle of a job to change refrigerant tanks. The unit maintains a user selectable amount of refrigerant in an internal vessel, and signals when it’s time to change the supply tank, so no monitoring is required.
  • Automatic Air Purge: Eliminates damaging air without any monitoring of gauges or opening of valves.
  • Automatic Oil Drain: The unit automatically drains system oil captured during recovery, and the display reminds you to empty the bottle. Graduations on the container clearly show you how much oil needs to be replaced.
  • Refrigerant Charging: Has never been this easy. Select a charge mode from either the high side, low side, or both. Accuracy features eliminate guesswork!
  • Refrigerant Management Systems: New and improved, system displays refrigerant use and monitors remaining filter life. Prompts appear when 1/3 of filter life remains.
  • Vacuum Function: Defaults to 15 minutes, but is programmable up to 99 minutes. Remaining vacuum time is displayed on the screen.
Robinair Is Ahead of the Game!
• One machine to safely service both conventional and high voltage A/C systems.
• Menu selectable function that gives the user the ability to clear any residual oil from the A/C Recover, Recycle and Recharge machine's fluid circuit and hoses minimizing risk of oil cross contamination.
• Meets new refrigerant recovery standards J-2788 for high voltage compressors.
• A/C capacities database (optional)
• Automatic air purge.
• Recovery accuracy ± 1.0 oz.
• Charge accuracy ± 1/2 oz. Higher accuracy for today's low volume A/C systems

• Voltage: 115 volt, 60 Hz
• Refrigerant container onboard: 30 lb. (14 kg) vessel (source tank not included)
• Operating range: 50 – 120° F (11– 49° C)
• Pump-free air displacement: 1.5 c.f.m. (36 L/minute)

In June 2005, the Society of Automotive Engineers (SAE) started a research program to reduce the emissions of R-134a. The program, called I-MAC (Improved Mobile Air Conditioning), was tasked with cost effectively improving R-134a systems while reducing refrigerant emissions. The I-MAC members have pledged to design smaller systems with fewer leak points and improve service equipment. As a result of this program, the SAE recently approved tighter standards for automotive A/C recovery, recycle and recharge equipment. The new standard, SAE J-2788 requires that all service equipment manufactured after November 1, 2007, must recover 95 percent of the refrigerant and recharge to within 1/2 ounce.

How will this affect ME?
Up until a couple of years ago, R-134a was cheap and plentiful. Today it’s a different story. Refrigerant is much more expensive and not always available. The Robinair 34988 recovers up to 20 percent more refrigerant, which means it will cost less to recharge the system. The best charge accuracy that could be claimed by older generation service machines is +/- 1 ounce, a 3 percent error on a two-pound system. That same charge accuracy on a 14-ounce system is over twice the error (7 percent).

Early R-134a systems could still provide some cabin cooling when they were 4-6 ounces (12- 18 percent) low on refrigerant. However, new designs are so efficient, they do not have reserve refrigerant, and charge accuracy will be critical. In the shop, the Robinair 34988 will recharge the vehicle to within 1/2 ounce of the charge capacity, and you will avoid the dreaded “call back”. As the shop owner, you will realize more profits per service by recovering more refrigerant and charging less. The savings will be obvious.
