We need to find a blower that will blow the right amount of air through the filters to create laminar flow. Instructions on how to figure out the maths of achieving laminar flow through a HEPA filter can be found in [http://fradnai.free.fr/docs/doc23.pdf this helpful PDF]. | We need to find a blower that will blow the right amount of air through the filters to create laminar flow.

In our case: | |||
To achieve 0.45m/s: airflow of 421m^3/h (248CFM) | |||
Filter pressure drop : 90Pa | |||
