Caryaire offers a variety of volume control dampers that can be operated using a robust handle (manual) or an electrical on/off, modulating or pneumatic actuator (motorized). These dampers come with airfoil or 3V blade designs in aluminium, steel and stainless steel construction. They feature robust axles, hardware and interconnecting linkage that is galvanized and not welded. Welding removes the galvanization and leads to corrosion of the metal and possibly failure of the blades to operate as desired.
