[0002] A high-throughput pressurized air filter is a device with high-efficiency filtering capacity and pressurizing function. It is mainly used to improve air quality and ensure the realization of a clean environment. It can effectively filter particulate matter, bacteria, viruses and other pollutants in the air. The existing gas is input through the air inlet to the inside of the shell for filtration through the filter element, so that the dust and impurities mixed in the air are filtered out by the filter element, and the filtered clean gas is discharged through the air outlet. Then, the pressurization system set at the air outlet is responsible for compressing the filtered air and generating a higher airflow pressure, and the clean air is delivered to the designated area through the pressurization system.
