[0002] A Roots blower is a type of screw air compressor that uses an opposed double-helix structure, characterized by high efficiency, energy saving, and high reliability. Its advantage lies in its output pressure and flow rate, typically higher than other types of air compressors, at the same input power. Furthermore, Roots blowers have strong resistance to contamination, making them widely used in industrial fields such as packaging, printing, and pharmaceuticals, as well as in pneumatic equipment and laboratories.
[0003] During operation, Roots blowers draw in various impurities and particulate matter, which can damage components such as bearings and impellers, affecting their normal operation. Therefore, an inlet air filter for Roots blowers is needed to prevent impurities and particulate matter from entering the blower. Existing inlet air filters for Roots blowers are usually fixedly connected to the blower body, making it inconvenient to install and disassemble the filter, thus reducing its practicality. Furthermore, the filter structure of existing inlet air filters for Roots blowers is usually fixed, requiring a significant amount of time to clean, further reducing the device's convenience.
