This product is worked by air compressor ,or use with double hose reel. No need high pressure machine. Conditions of Use: 1. Air source pressure: above 6kgf / cm2 2. Water source pressure: above 2kgf / cm2 3. Flow rate of water source: 15L / min 4 . Specification of water source pipe: 8mm (inner diameter) * 12mm (outer diameter Features: 1. Under the working conditions of the same air pressure and water pressure, the pulse force of the gun is greatly improved compared with the product, and the cleaning power is better than the ordinary car washing machine. 2. The front of the trigger of the gun is more in line with the principle of mechanics, and it is more labor-saving and convenient to use. 3. The gun supports low air pressure start (the lowest can be started at 3.5 kg) product advantages: 1. Water saving: the water consumption of the micro water-saving energy-saving high-pressure cleaning gun is only 10-13 liters, which is more than 90% water saving compared with ordinary car washing equipment. 2. Energy saving: The equivalent power consumption of the gun is only 0.6KW, which can save about 70% of the electric energy. 3. Safety: The safety of compressed air drive is better than other equipment, and there is no near-electrical contact, which avoids the hidden danger of hydroelectric hybrid operation. 4. Convenience: The matching application of the telescopic hanging drum makes the cleaning gun automatically telescopic in the working area, which is convenient and comfortable. Moreover, the water pipe is retracted into the hanging drum, and the double pipes are not easy to be damaged by aging. 5. Professional: Use pulse force to thoroughly clean the dust, mud and even floating mud attached to the body of the vehicle, and the high-pressure water is wrapped by air bubbles and does not hurt the car paint.
