Air Filter Test Machine
Fresh air system aerodynamic test bench/air filter performance test bench
Product Description
①Air duct system
②Pollutantgenerating device (KCL solid aerosol, gaseous pollutant, microorganism)
③Nozzle box air volume measuring device
④Upstream and downstream sampling ports
⑤Pollutant concentration tester
Purpose: In the process of product development and design, it can quickly and easily analyze the purification effect of the tested part on various pollutants (particulate matter, toluene, formaldehyde, TVOC and other pollutants), and can determine the air volume, resistance, one-time effectiveness and other properties parameters to facilitate the selection of raw materials, product process optimization and prototype performance.

Test method |
1. Place the tested part in the test section, control the temperature in the test room to 25℃±2℃, and the humidity to 50%±10% (according to user requirements). 2. Solid dust particle detection method (using standard cigarette smoke as the dust source of solid pollutants): Place particles of a certain concentration at the upstream end of the test section, use smoke or potassium chloride as the dust source, control the initial concentration of pollutants in the upstream end within the set range, and the solid pollutants are expressed as the total number of particles of 0.3um or above. Compare the initial concentration at the upstream end with the attenuated concentration at the downstream end to obtain the one-pass purification efficiency of smoke or dust of the air purifier.
