Overview
The CS3 runs off a 12V car battery, or off a wall outlet using the included 110V-to-12V converter. It reaches 4500 PSI, runs oil-free with fan cooling, and has a built-in oil/water separator. The big upgrade over the CS2 is auto-stop: set your target pressure and it shuts itself off, so you don't have to babysit the gauge. Safety hardware includes an adjustable pressure gauge, a safety valve, and a burst disc, and there's a wire spool to keep the cord tidy. GX rates the duty cycle at 30 minutes running and 20 minutes cooling. It's designed mainly for reservoirs under 1L. Always bleed it down after you switch it off, and never start it with pressure still inside.
"Airguns only. The auto-stop makes this a much easier machine to live with than the CS2. Respect the 30-on, 20-off duty cycle."
