Description

Technical Field

[0001] This utility model relates to a device for testing the filtration performance of air filters, and belongs to the field of air filter testing technology. Background Technology

[0002] An air filter is a type of filter, also known as an air cartridge, air purifier, or filter element. It is primarily used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. Air filter testing involves using professional testing methods to evaluate the filter's filtration performance, structural strength, and material durability to ensure it effectively protects the safe operation of equipment.

[0003] Chinese Patent Publication No. (CN 214408582 U) discloses an air filter performance and air intake testing platform, including a housing, a fixed plate, and a fan. The housing has a partition dividing the internal space into upper and lower layers. An air duct is installed on the partition, with a ventilation hole (110) at its center. The upper layer of the housing has a fixed plate with an adjusting screw fixed to its upper side. The lower end of the air duct's ventilation hole is connected to the inlet of a high-power fan. This invention uses a relatively portable mechanical operating platform, utilizing a wind speed sensor, an air pressure differential sensor, and a PM2.5 sensor to provide intuitive numerical displays of the air filter's performance and permeability. By analyzing and reading the values, the permeability and filtration accuracy of the air filter can be effectively analyzed, providing a convenient and intuitive understanding of air filter performance for general consumers or air filter retailers. The existing air filter elements are of different sizes, which makes it inconvenient for staff to fix the filter elements when testing their filtration effect, thus affecting the test results.
