The CS3 compressor is capable of 4500PSI. This has the autostop feature and it can be hooked up to your cars battery or use the power adapter to use it with your wall outlet. This has an effective built in moisture trap.
A safety valve, along with a burst disk making this a safer compressor then most out there. Plenty of youtube videos online showing how well this GX brand is... And this is a completely rebuildable compressor if ever needed. I've completely serviced the compressor and have properly lubricated it. It's been test ran and is within specifications.
This is ready to go and you'll have one of the easiest to use, serviceable compressors available today. I also have nearly all parts available to rebuild or repair the Gx Cs2 and Cs3 models. As with virtually all portable pcp compressors, this is designed for filling your PCP gun (not large bottles)... You now have an unlimited air supply unlike a bottle that only has what air is in it! If you want a portable compressor and must fill larger bottles over 2L look at the GX Cs4.
This is a high pressure, low volume compressor... It is not designed for nor intended to run pneumatic shop tools or any other high volume, low pressure item.
