Product Details
✓Why Choose GX: All GX compressors feature genuine specifications, such as power output, unlike others labelled as 350W yet failing to reach even 250W in reality. Most importantly, GX holds patented exclusive compression technology, such as the addition of roller bearings at the top and bottom of the connecting rod, allow for better movement and less wear on the rod and wrist pin, significantly extending service life and enhancing performance under high pressure.
✓Setting the Autostop Value & Built-in Oil-Water Filter :The filling of a rifle or pistol is hassle free with an auto shut off that the user sets at the desired pressure. This eliminates the user from having to watch the fill pressure gauge as the compressor does its job. It also features the moisture filter which is better for your airgun or scuba tank( not certificated). Suggest to buy GX professional external filter if you need enhanced filtration performance.
✓Oil-Free & Water-Free & Built-in Fan Cooling for Long Life : This portable pcp air compressor does not need oil, clean and hygienic, easy to operate.This will save you a lot of energy in future . External converter makes easy to replace new converter in future.
✓3 Type Safety Device Design & Convenient Wire Spool Design: Adjustable pressure gauge , safety valve and burst disc makes this air compressor pump more safe. With the wire spool, you don't need to worry about the wire winding and it also looks great.
✓Inflation Speed: This pcp compressor was designed mainly for inflating less than 1.5L tank. Fill a 190cc tank from 1800psi to 3300psi is a swift 2:30 minutes; Filled a 480cc carbon bottle from 1800psi to 3500psi is in a mere 8:30 minutes. The duty cycle of the machine is 50 minutes run / 20 minutes cool. This allows for filling of larger tanks ( suggest max 1.5L) as long as the compressor is allowed to cool.
✓Update :Compare with CS3 verison, the only difference is that CS3-I changed the home 110V-12V converter to inside the machine. ATTENTION: Please release the bleed valve first after turning off the switch , and do not start it when there is still air pressure inside your compressor ( include during the cooling down cycle).
