What is the minimum torque required to operate Honeywell dampers?
The minimum torque required to operate Honeywell dampers is 12 lb-in., regardless of the damper size or type. The M9174C1025 with its 75 lb-in. rating far exceeds this minimum and is suitable for larger, higher-pressure damper applications. (Page 36)
