The AC400 is a fully automatic R-134a recovery, recycle, and recharge machine built for shops servicing standard and hybrid vehicles, delivering a 95% recovery efficiency rate on a walk-away cycle — connect the machine, set the parameters, and return when the job is done. It handles the complete A/C service sequence in a single automated run: recovery, recycling, evacuation, leak testing, and recharge, with automatic oil drain and fresh oil injection that measures how much lubricant was removed and puts the correct amount back into the system. A built-in thermal printer outputs a service record at job completion, and an onboard capacity database covers passenger vehicle refrigerant and oil specifications without manual lookup.
The automation extends to the details that slow down manual machines. An automatic internal tank refill keeps the service running without stopping to top up the refrigerant supply mid-job. Automatic air purge prevents air accumulation in the internal tank — a common source of inaccurate recharge weights on machines that require manual purging. Onboard electronic scales measure refrigerant by weight for accurate charge delivery, and a vacuum leak test identifies gross system leaks before refrigerant goes back in. For shops that prefer direct control, a manual mode gives the technician step-by-step operation alongside the standard one-button auto cycle.
The AC400 is a strong fit for independent repair shops and dealership service departments running R-134a A/C service on a mixed fleet of conventional and hybrid vehicles, and for high-volume operations where the fully automatic cycle and walk-away capability keep technician time on A/C jobs to a minimum.
