【High Efficiency】This 550w diaphragm vacuum pump adopts a pure copper motor and highquality bearings for stable operation, with a rated speed of up to 1440 rpm and a vacuum flow rate of 67L/min (2.4CFM). Meanwhile, the aluminum alloy shaft in the middle is solid, which speeds up the air conduction to improve the working efficiency.
【Overheat Protection】It has a built-in thermal protector. When the temperature reaches 135°C±5°C/275°F±41°F, it automatically cuts off the power supply to prevent the motor from burning out due to high-temperature operation.
【Low Noise】The external silencer and the thickened wall ensure good noise reduction, giving you a quieter and more comfortable working environment. The silencer also has a filtering performance, making the input air pure.
【Easy to Carry】With its small size(11.02*7.48*5.7in) and lightweight(24.25lbs), and without an air tank, you can easily carry it to any workplace.
【Application】It can be used for gas tightness experiments, vacuum suction, food processin. It is suitable for semiconductor automation equipment, packaging machines, labeling machines, spraying machines, robotic arms, etc.
