Maintaining a positive pressure differential is a fundamental requirement in cleanroom engineering to prevent the ingress of contaminants into controlled environments. This calculation assists process engineers in sizing supply fans by balancing the fixed exhaust rates against the calculated leakage flow through structural gaps and penetrations.
