## Description

GX Pump CS4-I compressor

Review: Any good - Excellent product excellent service brilliant machine very quiet fills at a nice slow fill thanks again Keith
Review: Soooo glad I bought this compressor! In recent months I've bought three different budget level compressors and had problems with each of them (wouldn't work, or did but abruptly stopped working etc.) and so returned each of them; which I really don't like to do as it takes added time and energy. So I decided to spend the extra money on this one, hoping for the extra cost there would be no more issues... and I was right! Three or four times more expensive than the others but definitely worth it to have ZERO issues! Works like a charm. Highly recommended.

## Features

- This CS4-I PCP compressor has a new upgraded 350W motor , and adopts four-stage compression technology. It is very stable when working, and it is very quiet with only 70db. Maximum filling 5800Psi/40Mpa.Notice :First confirm the maximum safe pressure of your gas cylinder, do not over-inflate, otherwise it will cause safety problems. At the same time, it is equipped with a double-pointer pressure gauge, and the two-level setting auto-stop pressure, which is more secure.
- A water tank and a grease tank are designed on the top of the compressor. The excellent cooling can achieve 5 hours of continuous work and can fill a maximum 6.8L gas cylinder. Note: For the first use, it must be filled with about 500ml of neutral distilled water or antifreeze ( PH is about 7). Note: 1) you can only add antifreeze if it freezes in your area in winter. 2）:Do not turn the grease knob until after 6 hours of use, otherwise will cause bad performance. then turn it one turn every worked for 6 hours.
- 15% Faster Filling Speed: Filling 0.5L tank from 3000Psi to 4500psi ,only needs 4-5 minutes. Filling 0.5L from 0-4500psi, only needs 14-16 minutes. Filling 6.8 liter bottle from 0-4500psi ,2 hours and 40 minutes.
- Built-in 110v to 12V DC Converter: Compared to the GX E-CS4, the CS4-I has a built-in converter for greater convenience. You can use car battery or household outlet as power supply. The machine is also equipped with a built-in oil-water separator which never needs to be replaced, so you don't need to buy other external oil-water separators.
