Io Hvac Controls HD-NA-1614 Zone Damper 16x14 No Actuator

Product Description

The IO HVAC CONTROLS HD-NA-1614 is a two-position zone damper sized for 16 x 14 inch duct applications, supplied without an actuator. It accepts a 5/8 to 1/2 inch shaft and is designed to regulate airflow in zoned residential or light commercial HVAC duct systems. Zone dampers like this one are the mechanical backbone of multi-zone forced-air systems, opening and closing to direct conditioned air where the zone controller calls for it. The HD-NA-1614 ships actuator-free, making it the right choice when the installer is matching an existing actuator on hand or specifying a separate actuator to meet system voltage and torque requirements.

This damper is suited for installation in rectangular duct runs in forced-air heating and cooling systems that use zone control boards or thermostatic zone panels. The no-actuator configuration gives contractors flexibility to pair the damper blade and frame assembly with a compatible two-position or modulating actuator of their choosing. It is typically installed by HVAC technicians during new zoning retrofits or when replacing a failed damper blade assembly in an existing multi-zone system.

Key Features

• Duct opening size of 16 x 14 inches fits standard rectangular duct runs
• Ships without actuator, allowing pairing with a separately sourced two-position or modulating drive
• Shaft size range of 5/8 to 1/2 inch accommodates common actuator coupler sizes
• Two-position operation opens or closes fully in response to zone demand
• Package dimensions of 18 x 23 x 8 inches; ships at approximately 8 pounds

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular duct systems requiring a 16 x 14 inch two-position damper with a 5/8 to 1/2 inch shaft interface.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zone control panel before cutting into the duct or wiring any actuator. The actuator must be sourced and installed separately; confirm actuator voltage and torque rating match the zone board output before mounting. Duct connections should be sealed per local mechanical code requirements to prevent air bypass around the damper frame.
