A fume hood is a commonly used laboratory equipment that needs to exhaust harmful gases and clean and discharge pollutants during the experimental process.

Working principle: The air is sucked into the static pressure box by a low noise centrifugal fan at the top, and evenly blown out through a PVC pipe at the top (connected to the outdoor exhaust pipe), forming a negative pressure air curtain in the original experimental area. The original natural air or polluted air in the working area is removed, and the ideal space can be reached and maintained within five minutes after starting up. The air volume is adjusted using a light touch switch, and the wind speed in the packaging work area is ultimately in an ideal state.

Product Features

The frame is made of dust-free and fire-resistant high-density board material, and the experimental area is covered with stainless steel veneer. The surface is treated with electric spray, and the surface is smooth, dust-free, beautiful, and sturdy.

A system of water, electricity, gas, and ventilation, equipped with multifunctional power sockets, facilitates the use of other electrical equipment in the laboratory process. The use of a quick opening valve facilitates the use of water during the experimental process. The front baffle is a movable glass door, and the top is a low-speed exhaust fan, which can smoothly discharge harmful odorous gases during the experiment. The bottom of the working face is equipped with a stainless steel sink, which can discharge disinfectant and experimental residue from a row of sinks through water washing, maintaining a safe and reliable experimental environment.
