Experimental comparison of chemical filter performance indexes between aviation and industrial clean workshops

Tests and compares the efficiency, resistance and pollutant tolerance of aviation filters and industrial clean workshop chemical filters for ventilation, and concludes that the aviation filter features higher efficiency, lower resistance, but weaker pollutant tolerance. Provides a new evaluation index of chemical filters, which comprehensively considers the performance of filter efficiency, resistance and pollutant tolerance. Evaluates the performance of aviation filters and industrial filters with this index, the results show that the industrial filter can adsorb 114 mg of toluene with 1 kJ energy consumption, while the aviation filter can adsorb 369.1 mg of toluene, which is 3.2 times of that of the industrial filter, so aviation filters have better performance.
