Specification Brand : ZJchao BulletPoint : Pumps BulletPoint1 : Working Principle: Compress the air with a fixed volume in the pump chamber (compression suction port close, slight open positive pressure at the port), stretch (compression port close, negative pressure suction port open). Under a pressure difference, the air pressure (suction) enters the pump chamber and is discharged from the port. BulletPoint2 : DC Motor Drive: The negative pressure vacuum pump is driven by miniature DC motor, which drives the internal mechanical eccentric motion. The eccentric motion drives the internal reciprocating motion of the diaphragm. The design of a great starting moment is easy for starting and high efficiency, which can keep it working perfectly even is lower ambient temperature and lower volt. BulletPoint3 : High Performance: This micro vacuum pump has a suction of 5L/min, a vacuum degree of 65kPa, a maximum pressure of 120kPa, low noise, low power consumption, and is particularly suitable for high negative environmental needs. The oilless vacuum pump does not pollute the medium, requires no maintenance, can work continuously for a long time, which is stable and reliable. Equipped with bracket for easy fixation. BulletPoint4 : & Stable Operation: Built with a reinforced aluminum alloy casing, this auto AC vacuum pump efficiently disperses heat for durability. Its intake filter and trap effectively against impurities and oil mist to maintain optimal performance BulletPoint5 : Wide Application: This micro vacuum pump is suitable for electrical products, industrial products, vacuum preservation machine, gas conversion and emission device, gas analysis and sampling, instruments and other fields.
