Portable 12V PCP Air Compressor Air Gun High Pressure Pump Transformer 110V. Multiple power sources? This high-pressure pump is equipped with a transformer, which can be used on three voltages: DC12V/ AC110V/ AC220V, so it is convenient for you to use it anywhere without voltage limitation. Air cooling system? This duct is equipped with a built-in cooling fan, which has the characteristics of fast heat dissipation, not easy to oxidize, and long service life. Fast inflation speed? The maximum pressure of this duct is 4500PSI, which makes it only takes 15min for the pressure of a 0.5L diving bottle to rise from 0MPa to 30MPa. Explosion-of valve? This duct is equipped with an explosion-of valve. When the pressure reaches about 32MPA, the rupture disk will break and release the pressure by itself, making it safer to use. Pressure display? This duct is equipped with a LCD screen, which can display the pressure value of the high-pressure pump air pipe, which is convenient for you to view and adjust to meet the pressure value required for different tasks. Oil-water separation? This duct is equipped with an oil-water separator, which is widely used in diving cylinders, fire-fighting cylinders, paintball shooting, leak detection, pressure testing, and can also be used in cars, trucks, trucks, kayaks, Various balls, etc. High Power? This duct is a 300W high-power duct with a fast inflation rate, up to 15min/0.5L tank. Portable? The volume of this duct is: 320260260MM, and the weight is: 5.2kg. Compared with the traditional high-pressure pump, this duct is small in size and easy to carry. Working pressure:4500PSI /30Mpa/300Bar. Cooling system:Fan cooling. Charging rate:15min /0.5L tank. 8MM quick connect female. Oil-water separator (with pressure relief screw). 750MM high pressure hose. We are the honest and trustworthy supplier.
