Filter ventilation efficiency
Filter ventilation efficiency
(OP)
Hi! I'm an architect working on a natural ventilation building. We are proposing aluminum metal panel filters (Airguard), to block some dust and sand.
I would like to know if someone can help me to calculate the porosity of the filter wich id formed of pleated and flat screens . The only thing I have from the specification data is the pressure drop.
What I need to know is the % of ventilation that I will miss due to the filters.
Thank you very much ,
Beatriz

RE: Filter ventilation efficiency
If you were to ask this same question in an HVAC fourm you would be told:
That with only the information you have provided it would be impossible for anyone to give you a useful reply.
That pressure drop is a function of flow.
That "% of ventilation" has no inherent meaning.
That "porosity" is not typically a term used when discussing ventilation filter performance.
That the filter manufacturer datasheet will have information of need.
