This high compressed air pump is made of high-quality stainless steel and copper, which is strong, durable, and not easy to deform. The working pressure of this product is 30Mpa/300Bar/4500PSI, which is high enough to meet your demands. It only takes 8 minutes for this product to achieve fast inflation of 0.5L/0.11gal, which is fast and can save you a lot of time.   Key Features Good Materials: This product is made of high-quality stainless steel and copper, which is strong, durable, waterproof, high temperature resistant, and not easy to deform. The thickened fuselage can resist high temperature, oxidation, and high pressure, which can prolong the service life of the product. Strong Power: The copper motor has high conductivity and stable performance, which can bring strong power to meet your daily needs. High Efficiency: The copper motor has high conductivity and stable performance, which can bring strong power to meet your daily needs. It only takes 8 minutes for this product to achieve fast inflation of 0.5L/0.11gal , which can save you a lot of time and electricity. Real-time Display: This product includes a temperature display screen and a pressure gauge, allowing you to know the temperature inside the machine and the real-time pressure, which is easy for you to monitor. High Safety: This product doesn't have an exposed copper core, which can effectively prevent power leakage. Meanwhile, the positive and negative terminals of the quick-draw plug never intersect, which can make every inflation safer. Good Heat Dissipation Ability: The built-in cooling fan and the fan heat holes on the side of the product greatly improves the heat dissipation ability and keeps the product working constantly, which can extend its service life. Less Noise: The noise during the operation of this product does not exceed 80db, which is very small and can give you a quiet environment. Filter Function: The filtering device on the product can effectively filter oil, water, and impurities from the gas, making the gas purer. It can also efficiently prevent oil and moisture from corroding this product. Convenient to Use: This product can also support 220V household power or 12V car power to achieve convenient and fast inflation at any time and anywhere. The battery clip delivered with the product allows you to take the electricity in the car. Application It is suitable for filling high-pressure gas cylinders with a capacity of 2L/0.44gal(UK) and below.
