Rectangular air damper BIxW / RTS / IE series

Opposed blade dampers are built such that adjacent blades rotate in the opposite, or opposed, direction. This style of operation is the best selection for an outlet damper because it offers good control over the entire operating range and maintains an even distribution of air downstream from the damper. The blades are airfoil shaped to minimize the flow restriction of the damper in the open position. Commonly used for cold starting on many air and process gas systems, opposed blade dampers maintain even air distribution downstream of the damper.
