Hence, it will ensure complete protection of the fume hood and can be quite effective when using with biologically toxic elements.
Ducted Fume Hood:
These fume hoods can offer a lot of protection because they are equipped with ventilation systems that are located on the outside of the lab environment. These types of ventilation systems can be quite useful in labs that are chemically toxic and create a lot of dangerous fumes. In a lot of ducted fume hoods, there is a system of by-pass that can help to provide consistent airflow in multiple sash positions. Such a design can provide a lot of protection to the workers and will not consume too much energy.
Ductless Fume Hoods:

Extractor Systems:
In these fume hoods, you will find a better ventilation system towards the center or source of the contamination. The extractor system is positioned in such a way that it can facilitate the easy and quick removal of all fumes and airborne particulate matter. Such systems can be used in labs where you do not have the infrastructure for installing conventional hoods inside the labs. You can use these hoods if you have a small lab.
