Paper Abstract

The purpose of this study is to systematically evaluate the performance of a portable chemical fume extractor used for cleaning chemical fume in small work places. Four chemical liquids, a closed chamber, and a metal-oxide sensor were used to evaluate its performance. The experimental results show that the unit under test is able to extract high concentrations of the tested chemical vapors and the cleaning processes take 5 minutes in average to clean out a strong-smelling fume concentration of 29 ppm. The performance is evaluated in terms of the cleaning efficiency (η) and clean air delivery rate (CADR).
