D2 Control Damper

D2 Control Dampers are ultra low leakage control dampers that include blade and jamb seals. These dampers are ruggedly built with Three-V style blades for application as automatic control or manual balancing dampers in low to medium pressure and velocity systems. A wide range of electric or pneumatic actuators are available for these models. 

Features & Benefits:
  • Standard frames utilize heavy-duty 5 (12.7 cm) x 1 inch (0.25 cm) 16-gauge galvanized steel hat channel frame, designed for installation inside ductwork, have reinforced corners, and low profile head and sill on dampers less than 17 inch (43.2 cm) high
  • Stainless steel and aluminum (14- and 12- gauge galvanized steel only)
  • Single flange (either side of frame) or double flange (both sides of frame); flange has an additional 1-1/2 inch on each side
  • Standard three-V blades are fabricated from a single thickness of 16-gauge galvanized steel incorporating three longitudinal structural V-grooves (each running the full length of the blade); blade also has low to medium velocity and pressure capabilities
  • Square plated 1/2 inch (1.3 cm) diameter steel axles positively locked to the blades eliminate slippage between blades and axles
  • Removable shaft extends 6 inches (15.2 cm) beyond frame (optional stainless steel construction available)
  • Molded synthetic (acetal) bearings rotate in a polished extruded frame raceway, which provides extremely low friction and long operating life (bronze or stainless steel bearings are optional)
  • Blade-to-blade linkage (for parallel or opposed blade action) is concealed within the frame
  • Linkage is engineered to accurately control each and every blade without need for adjustment (plated steel construction ensures a long corrosion free life)
  • Flexible stainless steel compression-type jamb seals (between blade ends and side frames) and extruded vinyl blade seals (between blade edges) reduce leakage (silicone or blade seals are optional)
