High Performance Control Dampers

Nailor high performance control dampers are ideal for use in high velocity, medium pressure commercial and industrial HVAC systems. Standard features include a rugged galvanized steel hat channel frame with superior structural strength, no-maintenance concealed linkage located out of the airstream, totally enclosed within the damper frame, and heavy duty airfoil blades that combine superior rigidity and deflection resistance with low pressure drop. Extruded aluminum airfoil blade models with optional insulated blades and/or frame available.
