Blower Side Chanel is a type of side channel blower, this tool also known as a vacuum pump or vacuum compressor, can produce pressures that are significantly higher than industrial fans. However, side channel blowers produce lower airflow than, for example, centrifugal fans. The principle of operating a vacuum pump has its own technology: the air is sucked through a fast turning propeller impeller. After this, the air in the side channel blower is pushed and compressed out by centrifugal force. This flows through the side channel back to the inside of the vacuum blower and is compressed again between two further blades
