For Truck, Bus & Heavy-Duty Applications...
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 include a Large capacity, 50lb. removable tank and liquid pump for larger A/C systems, typically found in buses. A Nitrogen port to dry and leak test A/C systems. Fully automatic recovery, system evacuation, leak testing, refrigerant charge and oil drain/inject. Optional printer for capturing and retaining vehicle service data.
Proven technology simplifies service!
- Microprocessor — Controls functions; prompts lead you through programming and also signal when it’s time to change the filter-drier, vacuum pump oil, and compressor oil.
- Fully-Automatic Function — Program to recover, vacuum, leak test and charge without operating panel valves
- Electronic Scale — Makes it simple to recharge to factory specifications; also weighs recovered refrigerant and provides tank overfill protection.
- Vacuum Pump — 5 CFM has the capacity to thoroughly evacuate the system, readying it for recharging.
- Single-Pass Recycling — Makes an initial pass through the filter-drier.Multi-Pass Recycling — Additional recycling can be programmed in case of compressor burn-out, or other conditions.
- Heavy-Duty Filter-Drier — Removes moisture and acid from the refrigerant; can handle up to 200 pounds of recovered gas between changes.
- 50 Pound Tank — For large systems
- 18 Foot charging hoses are included — Extra long for cab and equipment compartments make recovery and charging easier.
