Feature:1. Adopt full hood air storage tank, stable air pressure, eliminate pulse, better performance.2. Low-noise design below 47 decibels, quieter during operation, without disturbing the printing work.3. The working pressure of the machine is adjustable, the barometer displays the pressure value, and has overpressure protection.4. The air brush adopts non-oil design and has stable fluid output performance.5. With automatic switch function, it can be started under pressure and can work continuously.Specification:Item Type: Air Compression MachinePower: 125WVoltage/Frequency: 220-240V/50HZ; 110-120V/60HZAutomatic Stop and Start: 4BAR (57PSI) stop; 3BAR (47PSI) startOvervoltage Protection Setting Value: 6BAR (86PSI)Flow Rate: 20-23L/MINPressure Adjustment Range: 0.2-6BARGas Storage Tank Capacity: 3.0LApplication: Suitable for high-definition picture requirements, stable air pressure and no impact, pressure-regulated and air-supply printing and large-caliber printing pens or multiple pens for art printing at the same time. It can be widely used in appearance coloring, decorating, and artistic art painting of beauty manicure, body painting, T-shirt printing, handicrafts, toys, models, etc.; it can also be matched with various small air nail guns, spray guns and other pneumatic tools; It can also provide gas source for industries such as medicine, environmental protection, chemical industry, scientific research and automation control.How to use: 1. The outlet of our air compression machine is usually 1/8in BSP, if you need 1/4in BSP or other NPT threads, you may need to fix other adapters on the outlet. Then you can connect different air hoses.2. There is a rubber sealing layer in the original air hose; the user can make the air tightness by hand and obtain good performance. If the air hose is not original, usually the air hose and the air compression machine cannot be sealed well. However, 100% air tightness is only effective for air compressors with automatic stop functions. PTFE tape can be used to prevent leakage. You can buy this elastic in all stores that sell hygiene products.3. Connect the air compression machine, air hose and spray gun (or other pneumatic tools), plug in the main power supply, turn on the switch, and then the air compression machine will start working. The pressure gauge will display the maximum pressure, and you can adjust the working pressure by adjusting the pressure regulator.4. Check for air leaks. Please do not use pneumatic tools first. When the pressure reaches the maximum pressure (automatic stop function), since the compression machine has no automatic stop function, please turn off the switch. Then check the needle of the pressure gauge. If the needle on the pressure gauge is very stable, it means that the air tightness is very good. If the needle drops quickly, there is an air leak somewhere in the connection. Please check and keep it tightly closed. Otherwise, any small leakage will affect the performance of the compression machine. (This may cause frequent automatic stops and automatic starts).5. The difference between the maximum pressure and the working pressure. The maximum pressure of the compression machine is the highest pressure it can build. When the connected spray gun is opened, it is under this pressure that the compressed air is first ejected through the spray gun nozzle. On the contrary, the working pressure is the constant pressure that the compression machine can maintain during the spray gun. On the other hand, the size of the working pressure depends on the nozzle diameter of the connected spray gun; the larger the nozzle diameter, the larger the amount of air that can escape, and the lower the working pressure of the compression machine.6. The compression machine has an air storage tank, which can store compressed air before delivery to the spray gun (or other pneumatic tools).Size: Approx. 31.3 x 13.5cm / 12.3 x 5.3in.Package List:1 x Air Compression Machine1 x User Manual
