Balancing a paint booth
A spray booth lives or dies on face velocity, which depends on supply and exhaust air staying in balance against filter loading. Size the high-pressure centrifugal blower to the booth's airflow and its static pressure together — as filters load, static rises, and a blower without pressure margin lets face velocity fall out of spec. The recommended approach specifies both numbers up front and picks a machine that holds airflow across the filter's life, so paint quality does not drift between filter changes.
