Description

technical field [0001] The invention relates to a filter test system, in particular to a filter test bench for ventilation. Background technique [0002] With the advancement of technology, the requirements of all walks of life are becoming more and more stringent, especially the requirements for the working environment. For example, air filter filtration devices have been widely used in clean workshops, clean workshops, laboratories and clean operating rooms. Therefore, testing and evaluating the performance of various filters such as air filters has become the primary issue. However, the original filter testing system in our country is the atmospheric method, and the dust holding capacity test is not carried out, and many tests are blank. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides a filter test bench for ventilation. [0004] The present invention adopts following technical scheme: [0005] A filte...
