A louver is a ventilation damper that allows passage of air restricting unwanted elements such as water, dirt, and debris from coming in.  Louver systems are installed on many multi-story buildings to ensure a smooth intake and exhaust of air, and also to provide strong tolerance against rain and noise operation.  They can also be used as a simple yet effecting screening solution for spaces to keep unwanted elements from sight.  Precisely selected and designed to suit the application and customer requirements.  Each louver has a row of blades that are meant to control or isolate the gas flow.

Self-supporting ducts without external mounting points or modifications required, fully welded, and comes with pre-drilled flanges to meet customer requirements.  Designed with double ply construction and strengthened shaft connections for bolt mountings.  These damper blades are designed with load-deflection capabilities under operating conditions.
