Louvers Engineering Guide Selecting the Right louver When selecting a louver , there are sev- First consideration: eral factors that should be considered: FREE AREA. a) Architectural considerations The minimum area through which air the louver height approaches 3 to 4 times b) Location can pass within a louver is called the the louver depth. Since the head and c) Performance free area of a louver1. sill of a louver are of a fixed height, the The free area of a louver is critical space they occupy becomes important, to its overall performance and must thus reducing considerably the amount a) Architectural considerations: of available blade face area (and thus Louvers can be built in multiple sec- be considered during its selection process.
• When installing a damper behind a fixed louver, the total pressure drop can be unpredictable. Use a louver with an integrated damper (combination louver) which is built as a single unit, the performance is tested and predict - able. • The pressure drop curves of louvers are based on free area velocity and vary very little, depending ...
