The rubber ring is a conical rubber ring, and the contact between the rubber ring and the filter fan is linear, with small contact area and poor stability. The above reasons cause unstable sealing, which easily causes "wind running" phenomenon, making it difficult to ensure the vacuum degree. During filtration, multiple vacuum pumps need to be operated, and the matching between the filter and the vacuum pump is about 1:1.5, resulting in high power consumption.
