Applications
Used in laboratory fume hoods, constant or variable air
volume installations for the control of supply and exhaust
air terminals; 53 lb-in (6 Nm) torque.
Models designe for applications that require the damper
to return to a fail-safe position when there is a power
failure; or models for fail-in-place.
