Feature: 1. 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.

Replace the breathing plug in the circle with the transport plug on the machine.3. Install the oil-water filter (the gasket is already installed at the factory and just need to tight it appropriately).4. Install the air outlet pipe. 5. Install the water pump. 6. Turn on the power supply of the air pump and start water circulation.7. Connect the outlet pipe to the container, tighten the pressure relief valve after starting the machine, adjust the required air pressure, and press the switch to start inflation..

When the pressure reaches 300BAR / 30MPA, the compressed air pump has an automatic stop function. But you must always pay attention to protect the machine.2. Please always monitor the temperature display and water supply when using the pump to avoid overheating.3. For smooth performance, you have to prepare cooling water and replace it every 30 minutes for an optimal cooling effect. Never start the machine before you have enough water prepared. 4. Dear customer, please rest assured to buy without worrying about the plug adaption. We will provide an adapter for you according to different country standard for ensuring its normal use. 5. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
