The Robinair 34788NI Fully-Automatic R134A A/C Machine is built to make A/C service faster, smarter, and downright effortless. Designed for professional shops, it handles recovery, recycling, and recharging automatically, so you can service more vehicles with less hands-on time. It even automatically injects oil back into the vehicle’s A/C system, eliminating guesswork and helping ensure every job is done right the first time.

What really sets the 34788NI apart is how much it thinks for you. The automatic air purge system removes damaging air without watching gauges or opening valves, while the 1.5 CFM dual-stage vacuum pump pulls a deep, reliable vacuum for consistent, high-quality results. Smooth, efficient, and shop-proven, the Robinair 34788NI turns A/C service into a push-button profit center your techs will love using.
