Full Steel Fume Hood

The fume hood is an essential safety equipment in a laboratory, primarily used for expelling indoor exhaust gases. It is a commonly used lab equipment designed for the expulsion of harmful gases and for cleaning and draining during the experiment process.
The main function of a fume hood: Primarily, the function of a fume hood is exhaust ventilation. In a chemistry laboratory, harmful gases, odors, as well as flammable, explosive, and corrosive substances can be produced during experiments. To ensure user safety and prevent the spread of contaminants from experiments, a fume hood should be used near the source of pollution. Previously, fume hoods were used sparingly, only in experiments involving harmful and dangerous gases or those that generate a lot of heat. The fume hood solely serves as an auxiliary function to the lab table.
The purpose of using a fume hood is to exhaust harmful gases produced during experiments, thereby protecting the health of the experimenters. This means that the fume hood must have high safety and operability, which requires it to possess the following functions:
Release Function: The system should be equipped with an institution to dilute the harmful gases generated in the fume hood by absorbing external air from outside the cabinet, and then exhaust them outdoors.
Non-backflow function: The function should ensure that the exhaust air from the fume hood, generated by the exhaust fan, does not reverse flow back into the room. To achieve this function, it is preferable to connect a fume hood to a ventilation fan with a single pipe. If a single pipe connection is not possible, it should only be used for connecting fume hoods in the same room on the same floor. The ventilation fan should be installed as close to the end of the pipe (or at the top of the floor) as possible.
Isolation Feature: A non-slip glass viewing window should be installed in front of the fume hood to separate the interior and exterior of the cabinet.
Supplementary Feature: Must have a duct or alternative device to draw in air from outside the fume hood when expelling harmful gases.
Controlled Wind Speed Function: An intake speed is required to prevent the release of harmful gases.
Thermal resistance and acid-base corrosion resistance: Some fume hoods require the installation of electric furnaces, and some experiments produce a large amount of acidic and alkaline harmful gases with strong corrosive properties. The countertops, lining boards, side panels, and selected water nozzles, gas nozzles, etc., of the fume hood should all have corrosion-resistant functions.
