The VAV High-Speed Damper Actuator is the key drive component that moves dampers and valves in a variable-air-volume fume-hood system, where the precision and speed of its mechanism directly determine exhaust performance.
It executes full 0–90° travel in roughly 1 to 2.5 seconds, fast enough to keep face velocity stable as the sash moves. Powered by AC24/DC24, it accepts 0(2)–10 Vdc or 4–20 mA control signals and delivers a torque in the 2.5–4 Nm class, suited to venturi and butterfly dampers.
This rapid, accurate actuation underpins the pressure-independent response that VAV systems rely on, helping maintain a constant fume-hood face velocity.
Pairing reliably with high-speed controllers and a range of damper types, it forms part of a safe, complete, and intelligent VAV variable-air-volume ventilation system.
