4500PSI 12V 110V PCP Air Compressor & Transformer 30Mpa High Pressure for Airgun. PCP AIR COMPRESSOR—- The PCP air pump is a compact compressor powered from a 110V outlet and operates from a 12V car battery. There is no need for oil, cleaning, and no need for an external water pump to cool. HIGH POWER FAN— The PCP compressor features a set-pressure gauge and temperature LED screen. The compressor can easily achieve 4500Psi, and the high-power fan can improve cooling efficiency. PORTABLE TRANSFORMER– The PCP air compressor is designed with a professional transformer that can decrease current loss and avoid damage for the pump to increase its service life. 8MM QUICK CONNECTOR— This pump has an 8MM quick connector. The inflation nozzle is an 8MM female port, which can be quickly connected and disconnected. Product name: High Pressure Air Compressor. Voltage: AC110V / DC 12V. Power supply: US plug. Cooling Way: Built-in Fan. Temperature display: LCD display. Noise:Less than 80db. Prodcut size:19cm16cm12cm/7.48″6.3″4.72. Net weight: 5.4kg. Package size: 30cm25cm25cm/11.81″9.84″9.84. The red terminal is positive (battery +) and black terminal is negative (battery -). Be sure to connect them correctly. Otherwise, the fan will not work, causing damage to the machine due to too high temperature. Connect one end of the high-pressure hose to the air outlet of the machine, and tighten the relief screw. It is normal when the beginning operating temperature of the machine quickly rises by 60? . It is only necessary to pay attention to keeping a single operation not more than 30min or 90? In daily use, so as to avoid long-time load operation from burning the motor. The maximum pressure of the machine shall not exceed 30MPA. The life will be linearly reduced if the machine is used with overpressure. With all things considered, it is suggested that the safe operating pressure be 25MPA. The machine must be started with 0 pressure. Upon completion of air inflation, immediately unscrew the relief valve to empty the high-pressure hose, to prevent long-time high temperature and high pressure from causing deformation to the check valve. Never remove the inflation head by force with pressure not emptied, otherwise, it will cause female head seal ring flyout and failure. 1 x PCP Air Compressor. 1 x 8MM Quick Connector. 1 x Accessories Kit. Professional personnel must be on duty during use process, because high pressure is serious. Immediately shut down the machine and unscrew the relief valve if something is wrong. It is suggested to keep normal 25MPA pressure and lengthen the machine life longth. The operating pressure shall be between 11.5-14V, a single operation shall not exceed 30min, and the cylinder temperature shall not exceed 95? (it may shut down the machine and start the fan only for cooling). Make sure that the operation shall not exceed 1min when the fan does not work and the air inlet is kept out. Otherwise, it will cause serious damage. We are always working according to international standards and serve our customers from all over the world.
