Internal cell of fume hood

Internal cell of fume hood

The inner compartment of a chemical fume hood contains, during work, the materials that are vaporized to it. Some of the requirements from the compartment include, among other things, that the direction of flow will be from the fume hood out, responsibility for the airflow in the fume hood, control of the volume of the fume hood noise and more.

The expectation from the fume hood compartment is to create uniform flow in a safe outward direction as this is done in the compartment whose upper part is sloped upward as can be seen in the image. Air flow unevenness and the presence of flammable materials in the cell can be a trap for materials that become explosive and dangerous. An internal chamber of a non-well-sealed or damaged fume hood can basically transform the filter itself from a useful tool to a dangerous one.

At the top of each compartment (which cannot be seen in the image) there is the Exhaust Exit. This part resembles an elongated cylinder and it leads the volatile materials out of the industrial structure and the fume hood itself. All the exit parts of all the fume hoods are connected to a top pipe system that transports all volatile materials outside the factory.
