Robinair AC1234-4SL – Premier Scale Lock R-1234yf Recover, Recycle, and Recharge Machine for Mobile Service

The AC1234-4SL is a fully automatic R-1234yf ACS machine with an integrated scale lock, designed for mobile service. The mechanical scale lock eliminates the need to recalibrate your refrigerant scale after transporting the machine long distances, saving time. Accessible from outside the machine, the lock secures the scale, preventing damage or inaccurate refrigerant measurement. The internal tank stays on the scale during transport.

A safe startup feature prevents the machine from powering on if the lock is engaged. Extra-long 12′ hoses make mobile service easier. An indicator light reminds technicians to lock the scale before transport, while special tie-down points and guidelines ensure your machine is safe and secure for mobile service.

AC1234-4SL meets or exceeds SAE J2843 standards for R-1234yf refrigerant recovery. The machine includes an integrated refrigerant identifier that samples the refrigerant in the vehicle’s A/C system prior to recovery. The AC1234-4SL is a highly accurate and reliable machine capable of servicing both standard and high-voltage vehicle A/C systems. The special AC1234-4SL version comes equipped with a mechanical scale lock, which prevents scale damage and is specifically designed to handle the rough day-to-day use of mobile automotive A/C service.
