Why choose our PCP Air Compressor? [Multiple power sources] This high-pressure pump is equipped with a built-in transformer, which can be used on three voltages: DC12V/ AC110V/ AC220V, so it is convenient for you to use it anywhere without voltage limitation. [Auto stop] This high-pressure pump has a built-in high-sensitivity pressure sensor with an automatic charging and stopping function. When the pressure reaches the setting value, the machine will automatically stop. You can complete the inflation without staring at the pressure gauge. [Air cooling system] This product 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 product is 4500PSI, which makes it only takes 15min for the pressure of a 0.5L diving bottle to rise from 0MPa to 30MPa. [Explosion-proof valve] This product is equipped with an explosion-proof valve. When the pressure reaches about 32MPA, the rupture disk will break and release the pressure by itself, making it safer to use. [Oil-water separation] This product 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.
