The ZD is a power close and spring open damper. It has a 24-volt motor used to control circulating air in HVAC systems and used when a normally-open damper is required. The ZD is typically used with the TrueZONE and other electronic zoning systems. |
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 with a third wire option M4 for LED open only light |
Reliable, strong, 24 V spring return motor |
Fail-safe, normally open operation |
Ordering Instructions: Order ZD (dimensions 1) x (dimensions 2), (motor is always mounted on dimensions 2 side) for example, ZD10x8 is a 10 in x 8 in damper with the motor on the 8 in side, but a ZD8x10 is an 8 in x 10 in damper that has the motor on the 10 in side |
Damper can be installed in any orientation (mounting side can be on either the bottom or the side of the duct) |
Motor or actuators mounting - side or top |
