Blade Type - Air Balance

Curtain Blade

Fast-acting design for fire barriers. Curtain blades consist of several slats linked together to form a fire-resistant curtain. These blades drop over the damper opening, slowing the spread of flames through fire barrier penetrations. Available for static or dynamic closure.

Curtain blades are available for UL-rated fire dampers.
