This product adopts an environmental protection system for upper exhaust air and lower air supply. The ambient air is pressed into the fume hood supplementary air box through the fan, and flows through the area that needs to be safe with a uniform cross-sectional wind speed, taking away the harmful gases in the area, thus forming a high-cleanliness working environment.

The fume hood is composed of the lower box, the upper box, and the operation panel. The box is made of aluminum-magnesium alloy main frame and galvanized sheet exterior, and is cured by epoxy resin spraying at high temperature, so as to effectively ensure the load-bearing performance of the product and prolong the long-term service life of the product.
