The Cool Air Duo-AC PRO is a fully automatic automotive A/C service station engineered for professional workshops. It handles vehicle cooling systems that use R134a or HFO-1234yf by utilizing two internal storage tanks, allowing technicians to work efficiently without switching cylinders. This machine automates the key stages of A/C maintenance—including refrigerant recovery, system evacuation, and precise recharging—using a high-performance 3/8 HP compressor and a 120 L/min vacuum pump. Its 7-inch touch display includes an automotive database that adjusts the service settings for each vehicle model to ensure quick and accurate operation. Designed for professional environments, the Duo-AC PRO includes real-time pressure monitoring, automatic stop functions, and a durable chassis with large wheels for workshop mobility. It is built for reliable daily operation in automotive service centers, dealerships, and repair shops.
