The Robinair AC1234-4 is the pinnacle of fully automatic R-1234YF recovery, recycling, and recharging technology for professional automotive service shops. Engineered to meet and exceed SAE J2927 and SAE J2843 standards, this machine delivers industry-leading performance with 98.5% recovery efficiency and charge accuracy within ±½ oz. Designed for both standard and high-voltage hybrid vehicle A/C systems, the AC1234-4 streamlines your workflow with fully automatic operation—simply program the service, walk away, and return when the cycle is complete. With an integrated refrigerant identifier that samples refrigerant purity before recovery, automatic internal tank refill, automatic oil drain with measurement, and programmable vacuum operation, this machine eliminates guesswork and maximizes productivity in your shop.
Professional-Grade R-1234YF Service Equipment
The AC1234-4 is a highly accurate and reliable machine built specifically for servicing modern vehicle A/C systems using R-1234YF refrigerant. With its integrated refrigerant identifier meeting SAE J2927 standards, the machine automatically samples the refrigerant in the vehicle's A/C system prior to recovery, ensuring you're working with clean, uncontaminated refrigerant. This critical feature protects your equipment investment and ensures compliance with environmental and safety regulations.
Capable of servicing both standard and high-voltage vehicle A/C systems, including hybrids and electric vehicles, this unit provides the versatility today's shops demand. Manual oil injection is performed using oil inject tools: part number 18465 for PAG oil and part number 18470 for POE oil, giving you full control over oil management for different vehicle types.
Fully Automatic Operation for Maximum Efficiency
Time is money in any professional shop, and the AC1234-4 is designed to save you both. The machine's fully automatic operation means you can program the entire service cycle and walk away—no constant monitoring, no interruptions. The unit handles recovery, recycling, vacuuming, and recharging without operator intervention, freeing your technicians to focus on other billable work.
Automatic internal tank refill ensures you never have to stop mid-service to fill the tank. The system intelligently manages refrigerant levels, pulling from the internal 30 lb DOT cylinder (with 21 lb usable capacity) as needed. Combined with automatic air purge functionality that removes the potential of air accumulating in the internal tank, you get consistent, reliable performance on every service cycle.
The automatic oil drain feature measures and displays exactly how much oil was removed from the system during service, giving you precise data for proper oil replacement and helping you diagnose potential compressor issues. The 355 ml (12 oz) oil bottle capacity accommodates a full range of service needs.
Precision and Reliability You Can Trust
Accuracy is non-negotiable when working with expensive R-1234YF refrigerant. The AC1234-4 delivers charge accuracy within ±½ oz, ensuring you're charging systems to exact OEM specifications every time. This level of precision minimizes waste, reduces callbacks, and builds customer confidence in your service quality.
Large Ø 100 mm (3.9 in.) gauges provide clear, easy-to-read system pressure monitoring, while the modern 5 × 9 cm (4.3-in. diagonal) graphical LCD display guides you through every step of the service process with intuitive prompts and real-time data. The programmable vacuum operation helps you reach the necessary vacuum level quickly in any condition, adapting to ambient temperature, humidity, and system size for optimal evacuation performance.
Built-in diagnostic functions include a system leak test to identify gross leaks before charging, saving time and refrigerant. The innovative liquid refrigerant flushing function allows you to flush A/C systems or individual components using liquid refrigerant instead of harsh chemicals—a cleaner, more environmentally responsible approach to system cleaning and component replacement.

Robust Construction for Daily Shop Use
Built for the demands of a busy professional shop, the AC1234-4 features durable construction with a 176 lb (82 kg) robust chassis and industrial-grade components. Measuring 107 cm × 56 cm × 80 cm, the unit is compact enough to fit in tight shop spaces while still housing a full-size internal cylinder and all necessary subsystems.
The machine operates on standard 115 VAC, 60 Hz shop power with 1380 VA power consumption, and functions reliably in temperatures from 10°C to 50°C (50°F to 122°F). With noise levels below 70 dB(A), it won't disrupt your work environment, and its maximum operating pressure of 31 bar (450 PSI) handles even the most demanding service scenarios.
2.75 m (9 ft) SAE J2886-compliant service hoses provide excellent reach and flexibility for servicing a wide range of vehicles without repositioning the machine. Every component is engineered to meet or exceed industry standards for safety, reliability, and longevity.
