This CS4 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 3L gas cylinder. Note: For the first use, it must be filled with 500ml of neutral distilled water ( can not contain impurities such as minerals )or antifreeze ( PH is about 7). Notice :Do not turn the grease knob until after 6 hours of use, otherwise will cause bad performance. then turn it one turn every 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. but filling 6.8L bottle from 0-4500psi ,will need 2 hours and 40 minutes .
