 Dampers have different usages in various industries; they’re installed in airway and change air flow or change its direction. Dampers are made of metal, polymers and wood and their blades can be fixed or movable. Fixed blade dampers are called louvers. Opening and closing dampers can be done manually or automatically. Automatic dampers are opened and closed with damper motor, air or oil jacks or mechanically. Dampers advantages are good airtight, low pressure drop, optimum strength, beautiful look, blades smoothness and …. . Damper blades’ edges will overlap to some extent and help better airtight. Daampers are put into 2 categories(in way of opening); first type blades are opened like Venetian blinds and second type blades are opened zigzag .Each of two types have its pros and cons. Plastic strip is used to have better airtight and better overall performance. Very big dampers (Macro Dampers) and very small dampers (Micro Dampers) are built and used today.
