A fume hood is a ventilated enclosure that collects chemical gases before taking them out of the room through an exhaust ductwork system. The exhaust system has a fan system that pulls gases out of the hood into the atmosphere. This protects lab workers from inhaling toxic gases thereby keeping them safe. One such system is the Wet Chemistry Laboratory Control Solution that has a movable sash in the front as well as an interior baffle. Also, the system has sashes that move either horizontally or vertically and are designed to protect the lab workers against the effects of the chemicals.
In addition, the system comes with slots and baffles that direct fumes towards the exhaust. The good thing is that, these baffles can be adjusted accordingly. However, users are advised to avoid closing them fully since that can block the exhaust path. The airfoil on the front of the hood allows for a smooth airflow as they do not have sharp edges that can cause air turbulence.
