High pressure air compressor 4500Psi adjustable pump for tires1、PCP(pre‑charged pneumatic) air compressor pump, can be widely used for fire fighting, paintball, leakage detecting, pressure‑tight test, automobiles, air impermeability test, pressure proof test. 2、Adjustable high pressure air pump, set the desired pressure needed for the tank being filled and let the machine do its work, easy and convenient to use. 3、Support automatic stop function, pump will automatically stop when the pre‑set pressure(maximum 30 MPa) is reached and any pressure under the maximum can be pre‑set for each tank to be filled. 4、It takes only 30 minutes to fill a 6.8L tank to 300BAR, quick‑fill performance, designed with two‑stage compression and a water‑oil separator for stable performance. 5、Self‑contained water cooling system, the system temperature is monitored by a battery‑powered digital thermometer. You will prepare the cooling water to be used by the system in a bucket that the unit will draw from and return water to for cooling and recirculation. 6、1800W motor all use high‑quality copper wires, with high‑pressure explosion‑proof valve, the machine will automatically protect itself after reaching the highest pressure, ensure stable operation. 7、Adopting water‑cooled and air‑cooled dual cooling configuration, lower temperature for better running, quick‑plug interface design, disassembly is more convenient and quick. 8、The cylinder adopts oxidation hardening process, durable, noise reduction treatment, double‑circulation built‑in air pressure treatment design, the gas can be filled more quickly.
