Robinair 34788-I

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.
