One Professional R-134a Machine. Built for Conventional, Hybrid & EV A/C Service.
Take your A/C service capabilities to the next level with the Robinair 34788NI-H Premier R-134a Refrigerant Recovery, Recycling & Recharging Machine — a fully automatic professional solution engineered to service both conventional vehicles and high-voltage hybrid/electric vehicle A/C systems.
From recovery and recycling to evacuation, leak testing and precision recharging, the 34788NI-H brings the complete R-134a service process together in one powerful machine. Its fully automatic operation allows technicians to program recovery, vacuum, leak test and recharge procedures without manually operating panel valves—helping streamline workflow in busy professional shops.
98.5% Recovery Efficiency
Efficiency matters when every A/C job consumes both technician time and refrigerant.
Robinair rates the 34788NI-H at an industry-leading 98.5% recovery efficiency, with charging accuracy of ±0.5 oz (±15 g) under specified operating conditions. That combination gives technicians the precision needed for today's increasingly sensitive automotive A/C systems.
Ready for Hybrid & High-Voltage A/C Systems
This is where the 34788NI-H separates itself from the standard 34788NI.
Robinair specifically identifies the -H model as Hybrid/EV capable, allowing it to service A/C systems using high-voltage electric compressors in addition to conventional vehicles. That makes it a strong choice for workshops preparing for a growing mix of gasoline, hybrid and electric vehicles.
Fully Automatic Service That Saves Technician Time
Set the service parameters and let the machine handle the process.
The 34788NI-H provides fully automatic recovery, vacuum, leak testing and charging, eliminating the need to continually operate panel valves throughout the service cycle. Visual and audible notifications tell the technician when service has finished or when the machine detects a problem.
The machine also includes automatic air purge and automatic internal refrigerant refill, helping reduce routine manual intervention and keeping the machine prepared for the next job.
