1.Strictly according to IATF 16949 quality certification system process production.     2. All products have passed the durability test, air tightness test, high and low temperature test and sensitivity test in the development stage, and 100% of online production has passed the air tightness test to ensure the best quality.                           3.Strong creative research and development ability, avoid all kinds of structural patent problems;                                                 4.Sound absorption and noise reduction polymer materials and fluid organic combination in the automotive chassis noise ≦50dB, it is very good to ensure the quiet and comfortable effect in the car.                  5.The dynamic power saving rate can reach 35% ~ 40% when the motor running frequency is between 15-20Hz by dc voltage regulated control system. The high polymer filtration system ensures that the compressed air is clean and clean without any pollution.                                           6.The speed of regulated DC motor is between 4000r/min and 10000r/min, and the output flow is between 40L/ min and 100L/ min (it can support a 3.5-ton car body within 2 minutes).                                              7.It is recommended to replace the distribution valve components when replacing the air compressure.
