Io Hvac Controls HD-NA-3016 Zone Damper 30x16 No Actuator

Product Description

The IO HVAC CONTROLS HD-NA-3016 is a two-position zone damper sized at 30 inches by 16 inches, supplied without an actuator and designed for use with a 5/8-inch to 1/2-inch shaft. Zone dampers control airflow to individual zones in a ducted HVAC system, opening or closing in response to a zone controller or thermostat signal. This damper ships without a motor or actuator, allowing the installer to pair it with the actuator of their choice to match the control system already in use. It is installed by licensed HVAC technicians in residential and light commercial zoning applications.

This damper is suited for rectangular duct systems where airflow must be directed or restricted at the zone level. It fits into two-position zoning setups where each zone is either fully open or fully closed based on a call for heating or cooling. The 30-inch by 16-inch blade size accommodates larger trunk ducts common in light commercial and higher-capacity residential systems. The no-actuator configuration makes it a practical choice when replacing only the damper blade assembly or when sourcing actuators separately.

Key Features

• Two-position operation for open/closed zone airflow control
• 30 inch by 16 inch blade size for larger duct applications
• Supplied without actuator for flexible pairing with existing or preferred controls
• Compatible with 5/8-inch to 1/2-inch shaft actuators
• Suitable for residential and light commercial zoned HVAC systems

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted HVAC zoning systems requiring a 30-inch by 16-inch two-position damper with a 5/8-inch to 1/2-inch shaft interface.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler and zone control panel before installing or servicing zone dampers. Ensure the duct opening matches the damper dimensions before mounting, and verify that the selected actuator shaft size matches the 5/8-inch to 1/2-inch shaft specification on this damper. Follow local mechanical codes and the zoning system manufacturer guidelines for actuator wiring and control integration.
