Robinair's No. 34788NI recycles, evacuates, leak-tests and recharges R-134a with improved 98.5% recovery efficiency for standard vehicles and fully automatic function. New design features a larger graphical display, automatic features including leak testing, automatic refrigerant refill, and oil drain/inject - putting A/C lubricant back into the system. Boasts the ability to add an optional printer, USB data sharing, refrigerant identifier, and wireless module for Wi-Fi or Bluetooth communication. Optional refrigerant charge and oil capacities database is available for North American market vehicles. Fully-automatic function allows you to program the machine to recover, vacuum, leak test and charge without operating panel valves. Automatic oil drain display reminds you to empty the graduated container to show the amount of oil to replace. With oil inject you can automatically inject oil back into the vehicle's A/C systems. Refrigerant and Oil Database features A/C system capacities for North American market vehicles (optional and not included with the machine). Save and print before and after service data which allows the user to store service information by vehicle and print this information to provide to a customer. Visual and audible alarm notifies the user when service is complete, or if a problem has occurred. Vacuum leak test monitors level after evacuation, and informs of possible leak. Automatic air purge eliminates system-damaging air without monitoring gauges or opening valves. Automatic refrigerant refill feature maintains a user-selectable amount of refrigerant in an internal vessel and signals when it's time to change supply tank. Vacuum feature defaults to 15 minutes, programmable up to 99 minutes, and 'remaining time' is displayed. Refrigerant charging features allows you to select a charge mode from high, low or use both sides. Refrigerant management system displays refrigerant use and monitors remaining filter life. Display is multilingual.
