ABOUT AIR FLOW HOODS
Working Principle
There are different kinds of flow hoods commonly used in the
laboratories. They are divided into three main classes.
Class 1. In these types of flow hoods, the air flows from the lab
towards the surface where the experiments are conducted
Class 2. In this flow hood, air flows from the lab towards the
chamber. Fresh air then enters the chamber from above. The exhaust
air is then HEPA filtered before release to the environment through
the exhaust fume hood. The air can also be recirculated inside the
chamber.
Class 3. These kinds of biosafety cabinets are used in labs where
delicate experiments are conducted. Both the air entering the
chamber and the air exiting are passed through HEPA filters to
ensure that it is free from contamination.
Uses
This kind of flow hood is not only used in biological labs. It is
also a standard component in electronic manufacturing labs where it
is used to create a non-contaminated environment that is required
during assembling of electronics.
The equipment is also essential in a microbiology lab. Laminar flow
hoods are used to ensure that the air required in handling specific
microorganisms such as antisera is clean and free from
contaminants.
A horizontal laminar flow hood is used in pharmaceutical companies
to create an aseptic environment for the handling of sterile
products. The horizontal laminar flow hood is fitted with HEPA
filters that continuously bathe the working deck with fresh air.
This aids in the removal of microorganisms that can interfere with
the experiments. The air from the laminar flow hood exits the
chamber via an exhaust fume hood.
