Vacuum feeding fan refers to the negative pressure Roots blower used in material transportation, which can also be called Roots vacuum pump.
The working principle of the vacuum feeding fan is a dust-free airtight pipeline conveying equipment which conveys particles and powder materials by means of vacuum suction. By using the difference of air pressure between vacuum and environment space, the gas flow in the pipeline is formed, which drives the movement of powder materials, thus completing the powder conveying. Vacuum transportation is pipeline closed transportation, which can eliminate dust pollution, improve working environment, reduce environmental and personnel pollution to materials and improve cleanliness. Because it is pipeline transportation, it occupies small space and can complete powder transportation in narrow space, making the workspace beautiful and generous, especially not limited by long and short distance. At the same time, vacuum feeder can reduce labor intensity and improve work efficiency; it is the most way of powder material transportation.
