The AC400D is a dual-refrigerant R-134a and R-1234yf recovery, recycle, and recharge machine built for shops that service both conventional and newer vehicles on a single piece of equipment. It delivers 95% recovery efficiency on a fully automatic walk-away cycle and switches between refrigerants quickly without a separate machine or manual circuit swap — the practical solution as 1234yf vehicles make up an increasing share of the service mix. It runs on 110V/60Hz single-phase power with a 3/8 HP compressor, a 16 gal/min vacuum pump, and a 22 lb internal refrigerant tank, and ships with a one-year labor, two-year parts, and three-year compressor warranty.
The automated sequence covers recovery, recycling, evacuation, leak testing, and recharge in a single cycle. Automatic oil drain and fresh oil injection measures how much lubricant was removed and returns the correct amount to the system. Automatic internal tank refill keeps service running without stopping mid-job, and onboard electronic scales weigh refrigerant to ±10g accuracy and oil to ±5g for precise charge delivery every time. A 4.3-inch color touchscreen at 480×272 resolution handles navigation and settings, a built-in thermal printer outputs the service record, and the onboard capacity database covers refrigerant and oil specifications for all passenger vehicles without manual lookup. A vacuum leak test identifies gross system leaks before refrigerant goes back in, and manual mode gives step-by-step control for technicians who prefer it.
The AC400D is built for independent shops and dealership service departments transitioning to a mixed R-134a and R-1234yf service workload, and for high-volume A/C operations that need a dual-refrigerant machine with fully automatic cycling and the accuracy of load-cell measurement on both refrigerant and oil.
