Interpreting Pressure Drop and Airflow for Filter Selection
Pressure drop and airflow aren’t afterthoughts; they’re the practical metrics you’ll use to pick a filter that actually meets your cleanroom’s needs. You’ll evaluate how much resistance the filter adds to the supply and how consistently it maintains required air movement. A higher pressure drop can reduce overall airflow, compromising contaminant control; choose a filter whose resistance aligns with your system’s fan capability and safety margins. Airflow targets, such as cubic feet per minute or air changes per hour, guide you to filters that sustain clean conditions without overstressing fans. Consider peak conditions, like startup surges, to avoid sudden performance drops. Verify that the selected filter supports predictable, uniform distribution of clean air, minimizing dead zones and ensuring consistent protection for occupants and processes.
