Fail-Safe

Explore our full range of damper fail-safe actuators for HVAC systems

Our set of damper fail-safe actuators is available in our IACS store.

These tools contain a system that allows the actuator to continue operating even if the power source is insufficient for whatever reason. For the best guidance on which part is necessary for your system, contact our technical department at IACS.

How a damper fail-safe actuator works

A capacitor is put in the actuator, which discharges the stored energy to a motor, causing the actuator to either fully open or fully close. View our IACS blog post to find out how a fail-safe actuator works.

IACS' Sales staff is happy to answer any inquiries you may have about price matching or inventory.
