GX Pump Professional-Grade Filter

Overview

A bolt-on filter for compressors that need better air than their built-in separator gives you. The body is thick-walled aluminum rated to 5800 PSI. Inside, a layer of activated carbon and a molecular sieve pull out oil, water, and particles before the air reaches your gun or tank. The patented pressure-maintaining valve holds air back until it builds to about 1800 to 2000 PSI. Filtering at higher pressure squeezes more water out. Always connect the compressor hose to the INLET side, and don't loosen the small factory-set nut on top. To change the media, remove only the large nut with holes. Mount it with the two included magnets or with screws through the base. On models with a built-in converter (CS3-I, CS4-I), keep the magnets away from the converter. On the CS4-I, use the side without the converter.

Roger's Take

"Cheap insurance for a $600+ compressor and a $1,000+ rifle. Dry air is what keeps seals and valves alive. Mount it standing up, or it won't do its job."

Will it fit my compressor?

GX says it fits the whole GX line (CS1 through the 5K) and most other PCP compressors with an M10x1 / 8mm output, with no adapter. The catch: it has to stand upright to separate water properly, so it only works on compressors you can mount it to vertically.
