The NitroFill AutoFill 1000 digital coin-operated air inflation system is designed to actually “sell” air. To use, simply select the desired tire pressure using the “plus (+)” and “minus (-)” buttons, slide the hands-free “Insta-Lock” fast-fill air chuck onto the tire valve stem and wait for the beep. The C1000 inflates or deflates the tire to the exact pressure specification in seconds. This station features advanced digital technology, with no pressure gauge to handle or watch, combined with NitroFill’s standard 1.5 hp, high-performance, oil-less compressor and on-board storage tank.
