Robinair AC1234-4 Recover, Recycle, Recharge Machine
Product Details
The Robinair AC1234-4 is a fully automatic refrigerant recovery, recycling, and recharge (RRR) machine designed for professional automotive A/C service using R-1234yf refrigerant. Built to meet SAE J2927 and SAE J2843 standards, it delivers high performance with up to 98.5% recovery efficiency and charge accuracy within ±0.5 oz.
Engineered for both standard and high-voltage hybrid or electric vehicle systems, this unit simplifies service with programmable, hands-free operation. Technicians can initiate a full service cycle—including recovery, vacuum, leak testing, and recharge—and return once the process is complete. Features like an integrated refrigerant identifier, automatic internal tank refill, and oil drain measurement help improve accuracy, protect equipment, and reduce downtime.
