Mastercool 69391 SparkFree TwinTurbo Refrigerant Recovery Machine for R1234yf

The Mastercool 69391 SparkFree TwinTurbo Refrigerant Recovery Machine is a professional-grade solution engineered specifically for contaminated mobile A/C systems using R1234yf refrigerant. This unit is a contaminated-recovery-only machine, designed to safely handle flammable and mixed refrigerants while meeting SAE J2851 requirements for automotive service environments.

At its core, the 69391 features a ½ HP oil-less TwinTurbo double-piston compressor, delivering one of the highest recovery rates available while eliminating oil contamination. The spark-free internal design allows safe operation with flammable refrigerants, including A2L and A3 classifications, making it a critical tool for modern automotive A/C service.

The system includes a stainless-steel ball valve manifold with large, easy-to-read 2½-inch gauges, allowing technicians to monitor pressures accurately throughout the recovery process. A built-in purge valve ensures complete removal of refrigerant from the condenser and internal system components after recovery is complete.

For safety and reliability, the Mastercool 69391 incorporates automatic overfill protection, stopping recovery at 80% tank capacity, along with a high-pressure safety switch and automatic low-pressure shutdown. The unit is housed in a rugged HDPE injection-molded case with integrated bumper guards, providing durability for both shop and mobile service environments.
