4,500 PSI max · Fan-cooled
12V120V220V Auto-stop
Compact fan-cooled 4500 PSI unit with a built-in power adapter. Runs on 12V, 110V or 220V. Made for filling airguns directly.
GX Pump CS3-I
The CS3 with the 110V converter built in. 4500 PSI, auto-stop, built-in oil/water separator.
Overview
According to GX, the only difference from the CS3 is that the 110V-to-12V converter moved inside the machine. Plug it into a wall or clip it to a 12V battery, with no separate power brick to carry. Everything else matches the CS3: 4500 PSI, oil-free fan cooling, a built-in oil/water separator, and auto-stop at the pressure you set. Safety hardware includes an adjustable gauge, a safety valve, and a burst disc, and there's a wire spool for the cord. GX rates the duty cycle at 50 minutes running and 20 minutes cooling (the CS3 listing says 30/20). It's designed mainly for reservoirs under 1.5L. Bleed it down after you switch it off, and never start it with pressure inside.
"Airguns only. Pick this over the CS3 if you'd rather not carry a separate power brick. Same compressor otherwise."
