Title: HVAC performance (CFM) vs filter state
Post by: organometallics on February 14, 2023, 01:52:25 PM
Hi,

Does someone have a plot showing how the air flow velocity changes as the filter becomes more and more restricted (dirty)?

I presume it slows down BUT because pressure increases, it should speed up?

thanks
