[Product Parameters :Standard voltage 12V, operating voltage 10.8-13.2V,Current 4.7A ( when the voltage 13.2V enough current to 4.7A)( Not the general domestic motor , this product is innovative design { right } double rotary motor,DC brushless type , after the carbon brushes are worn and the problem can not be used turbine , low -power high- quality assurance , 20,000 hours maintenance- promise does not exist ! Disguising ! )Most large air volume , maximum speed above 16,000( Under normal conditions , is about 12,000 rpm )Pressure around 4KpaDimensions Diameter : 60mm x 60mm length : 76mm, weight about 236 grams .Built-in two different independent motor speed (of high-speed ball bearing mounted 4 ) , two fans , two-sided blade reversal unique design , to ensure adequate air pressure . 5 blade fan inlet , outlet fan blades 7 , 7 blades into the wind turbine work at 16,000 revolutions per minute to start , and then after a reversal of 12,000 revolutions per minute increase fan pressure . Let supercharging effect to maximize !!Fuel savings of 5% -20 %. ( Depending on the specific vehicle condition )Reduce harmful emissions .Internal combustion engine to reduce carbon, prolong engine life.Enhanced engine power by 10% to 20 % at the start of the vehicle , the use of air conditioning or hard acceleration power increase
