Hi,
My name is Hany Saad and I work as an intern at the FabLab Amsterdam (Waag Society). Together with my colleague, I am building a laminar flow hood. During our research, we had the chance to disassemble an actual hood. It was a nice project, but it did left us with some questions.
When we opened up the back, we saw that the blower was attached directly on top of the HEPA filter. Next to the blower was a duct, which connected the inner workspace with the top of the cabinet through a filter. This filter on top also contained the airflow sensor.
My question is this: Can somebody explain to me how the air flows through this system? For us it was strange that the filter and the top were directly connected to each other. Also, the airflow sensor was attached to the filter on top, which seemed kind of odd (see sketch) I included pictures, plans and sketches of the cabinet. Don't mind the arrows,
Thanks in advance
