Airfoil blades, which have greater strength, produce less sound, greater sealing ability, and static pressure loss
The ability to easily butt to the back side of a louver for tight shut-off capability
Unique double edge blade seal design that enables higher pressure on either side of the damper to assist in blade to blade seal shutoff
Linkage concealed out of the airstream for low maintenance and reduced air turbulence
