Zonefirst ZDS-16X10 16WX10H Parallel 24V 2-Pos S/R

The Zonefirst ZDS-16X10 is a heavy-duty 16WX10H Parallel 24V 2-Pos S/R rectangular zone damper designed for reliable airflow management in residential and commercial forced-air systems. Constructed from extruded aluminum with 3-inch parallel blades, this side-mount unit is engineered for low-resistance operation and longevity in high-demand environments. The damper utilizes a 24V spring return actuator, providing a fail-safe "power-close, spring-open" configuration that can be field-converted for "power-open" applications in minutes. Ideal for HVAC zoning systems requiring precision, the ZDS-16X10 motorized damper features self-lubricating bushings and a synchronous motor tested to over 250,000 cycles. With a maximum static pressure rating of 1.0" W.C. and a 2-wire 24V connection, it integrates seamlessly with most standard zone control panels. This rectangular duct damper is 1/4" undersized to ensure a smooth fit during HVAC damper installation, making it a preferred choice for contractors focusing on system efficiency and temperature balancing.

• Rugged Construction: Built with an extruded aluminum frame and zinc-plated linkage for maximum durability in various duct environments.
• Fail-Safe Operation: The 2-position spring return mechanism ensures the damper defaults to a specific state during power loss for safety.
• Precision Control: Features a minimum position adjustment screw to allow bypass air, reducing the need for separate bypass dampers.
• Quiet Performance: Equipped with self-lubricating Delrin or brass bushings to eliminate mechanical noise during blade rotation.
• Ease of Service: The motor can be swapped in under a minute by loosening a single setscrew, minimizing downtime for field repairs.

Is the ZDS-16X10 compatible with my existing zone control panel?
Yes, as a 2-wire 24V AC component, it is compatible with most 24V residential and commercial zoning system controllers.

Can this damper be installed in any orientation?
While typically used as a side-mount (ZDS), the lightweight 1/16" aluminum zone damper frame allows for installation in any orientation within properly sized ductwork.

How do I adjust the minimum airflow setting?
The actuator includes a slotted set screw on the side. Adjusting this screw limits the blade travel when closed, allowing a specific percentage of air to bypass the zone.
