- Mechanical visual position indicator for damper status.
- Solid construction using extruded aluminum frame and blades.
- Parallel blade design for low leakage performance.
- Simple, easy-to-wire, two-wire installation.
- Reliable, strong, 24-volt spring-return motor.
- Fail-safe, normally open operation.
- Ordering Instructions: Order ZD (dimension 1) x (dimension 2). (Motor is always mounted on dimension 2 side.) For example, ZD10x8 is a 10" x 8" damper with the motor on the 8" side; but a ZD8x10 is an 8" x 10" damper that has the motor on the 10" side.
- Damper can be installed in any orientation (mounting side can be on either the bottom or the side of the duct).
