Io Hvac Controls sd-2412 Zone Damper 24x12 in Commercial

Product Description

The IO HVAC CONTROLS sd-2412 is a rectangular auxiliary zone damper designed for use in commercial HVAC zoning systems. Sized at 24 inches by 12 inches, this damper controls airflow through ductwork by opening and closing on demand from a zone control system. It fits into rectangular duct runs and works alongside thermostats, zone controllers, and bypass components to balance conditioned air delivery across multiple zones. Licensed HVAC technicians and sheet metal contractors typically install this damper as part of a multi-zone forced-air system.

The sd-2412 is rated for commercial applications, making it appropriate for light commercial buildings, office spaces, retail environments, and larger multi-zone residential installations where a full-sized rectangular damper is required. Its 24-inch by 12-inch rectangular profile matches standard commercial duct sizing, simplifying integration into new or retrofit duct systems. When a zone calls for heating or cooling, the zone controller signals this damper to open; when the zone is satisfied, it closes to redirect airflow.

Key Features

• Rectangular form factor sized at 24 inches by 12 inches for standard commercial duct fitment
• Auxiliary zone damper function for multi-zone HVAC airflow control
• Designed for commercial application environments
• Integrates with zone control systems for demand-based airflow modulation

Compatibility

Designed as an OEM-style auxiliary zone damper for commercial rectangular duct systems requiring a 24-inch by 12-inch damper in a multi-zone forced-air HVAC installation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and duct fabrication practices. Shut down the air handler and de-energize the zone control panel before installing or wiring the damper. Secure the damper into the duct opening according to standard sheet metal practices, ensuring an airtight fit to prevent bypass leakage. Connect low-voltage control wiring to the zone controller per the controller manufacturer's wiring diagram and applicable local codes.
