Industry-Leading Performance for Professional A/C Service
The Robinair 34788NI Premier R-134A represents the pinnacle of refrigerant recovery and recharge technology, delivering an unprecedented 98.5% recovery efficiency that sets the industry standard. Engineered for both standard and hybrid vehicles, this fully automatic machine streamlines every aspect of A/C service—from recovery and recycling to evacuation, leak testing, and precise recharging.
Designed for high-volume professional shops, the 34788NI combines robust construction with intelligent automation. Its large 5 cm x 9 cm graphical display provides clear, multilingual operation in English, French, Spanish, and Portuguese, while fully automatic functions eliminate the need to manually operate panel valves during service cycles. The machine's advanced refrigerant management system continuously monitors usage and filter life, alerting you when maintenance is needed.
Built to SAE J2788 certification standards, the Robinair 34788NI features a powerful 3/8 hp hermetically sealed compressor, a high-performance 1.5 cfm dual-stage vacuum pump pulling down to 29.9 InHg, and a substantial 30 lb DOT-certified internal cylinder. The 150 lb spin-on filter-drier ensures clean refrigerant processing, while 9-foot hoses provide excellent shop-floor maneuverability.
Key Advantages of the 34788NI
- Unmatched 98.5% Recovery Efficiency – Reclaim more refrigerant per service cycle than any competitor, reducing waste and operating costs.
- Fully Automatic Operation – Program complete service cycles to recover, vacuum, leak test, and charge without manually operating valves, saving time and reducing operator error.
- Automatic Oil Management – The graduated oil drain container shows exactly how much oil was removed, and the oil inject function automatically replenishes the vehicle's A/C system with the correct amount.
- Precision Charging Accuracy – +/- 0.5 oz charge performance at operating temperature ensures vehicles receive the exact refrigerant charge specified, optimizing A/C performance.
- Comprehensive Data Storage & Printing – Save and print before-and-after service data by vehicle, providing professional documentation for your customers and shop records.
Advanced Automation Features
The Robinair 34788NI is engineered to maximize shop productivity with a comprehensive suite of intelligent automation features:
Automatic Refrigerant Refill: The machine maintains a user-selectable refrigerant level in its internal vessel and signals when it's time to swap supply tanks—no constant monitoring required.
Automatic Air Purge: Non-condensables are automatically eliminated from the refrigerant without requiring technicians to monitor gauges or open valves, protecting A/C systems from contamination.
Vacuum Leak Test: After evacuation, the machine monitors vacuum levels to detect possible leaks before recharging, preventing wasted refrigerant and comebacks.
Programmable Vacuum Function: Defaults to 15 minutes with the option to program up to 99 minutes. Remaining time is clearly displayed throughout the process.
Flexible Refrigerant Charging: Select charge mode from high side, low side, or both sides simultaneously for maximum flexibility across vehicle types.
Visual & Audible Alarms: The machine notifies technicians when service is complete or if a problem occurs, eliminating guesswork and ensuring attention to issues.
Intelligent Refrigerant Management
The 34788NI features an advanced refrigerant management system that tracks usage and monitors filter-drier capacity. When 1/3 of filter life remains, the system prompts the operator to order a replacement, ensuring continuous high-performance operation and preventing contamination issues. The automatic oil drain displays the exact amount of oil removed in a graduated container, while the oil inject function precisely returns lubricant to the vehicle's A/C system—critical for maintaining compressor longevity.
Optional Enhancements
The Robinair 34788NI is designed to grow with your shop's needs. Optional accessories include:
- Refrigerant & Oil Database – A/C system capacities for North American market vehicles (not included with the machine, available separately).
- Optional Printer – Print before-and-after service reports directly from the machine for customer records and shop documentation.
- USB Data Sharing – Transfer service data to external systems for record-keeping and analysis.
- Refrigerant Identifier – Verify refrigerant purity before processing to protect your equipment and ensure quality service.
- Wireless Module – Enable Wi-Fi or Bluetooth® communication for enhanced connectivity and data management.
Built for the Professional Shop
Weighing 232 lbs and measuring 48.5 in H x 24 in W x 36 in D, the 34788NI provides a stable, durable platform designed for years of heavy-duty use. The machine operates reliably in shop environments from 32° to 120°F and runs on standard 125 VAC 60 Hz power. Its robust construction and SAE J2788 certification ensure consistent, compliant performance service after service.
Recovery performance exceeds 95% at 70 to 75°F in under 30 minutes, ensuring fast turnaround times during peak shop hours. The combination of speed, accuracy, and automation makes the Robinair 34788NI an essential investment for any professional automotive service facility.
