My factory,a drinking water plant,
(OP)
My factory,a drinking water plant, has ventilation problem namely ,the flow rate of air supplied to the plant is not enough (air change ?). I think this problem is couse by the filter area is not correct. How can I estimate the filter area, and what method I can check? note: The system consist of 4 blowers.





RE: My factory,a drinking water plant,
(airflow in cfm/ room volume in cu.ft)*60.
Check this link for required air changes. The values given are fairly good with some redundancy.

For filter area, filter manufacturers can best help you. You have to select that from pressure drop vs flow capacity curves of the filters.
