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.
