Coats Autoflate Digital Inflator. NO HOSES Just what you see in the picture. If any questions please contact me. Contact me before purchasing. With Autoflate, you can inflate tires without waiting by the tire changer. This means you can change the next tire while inflation occurs, increasing your productivity by 5%-10%. Set the pressure, attach the chuck, and press’Start’ – Autoflate does the rest. Accurate to +/- 0.5 PSI. Highly intuitive, easy-to-use design. Inflates a typical tire in 40 seconds (with 150 PSI inlet pressure). Heavy-duty grip chuck seals and holds on stem. Rounded grip chuck end prevents scratches in the stem area. Nitrogen-ready – a quick keypad sequence switches from Air to Nitrogen mode. UL / CSA / CE / ETL approved. Auto-start feature will start and inflate the tire to desired pressure automatically if the tire has air pressure when the chuck is attached.
