Io Hvac Controls EB-2616 Motorized Bypass Damper 26x16

Product Description

The IO HVAC CONTROLS EB-2616 is a heavy-duty motorized bypass damper designed for zoned HVAC systems. It automatically redirects excess conditioned air to prevent pressure buildup when zones close, protecting the air handler and ductwork from over-pressurization. Built for demanding residential and light commercial applications, this damper features an integrated motor that opens and closes in response to zone controller signals. At 26 by 16 inches nominal duct size and 16 pounds, it is engineered for permanent installation in main trunk or branch bypass configurations. Licensed HVAC technicians are the primary installers for this component.

This motorized bypass damper is suited for forced-air zoning systems where multiple zone dampers create variable static pressure conditions. It installs in the bypass duct run between the supply plenum and return plenum, maintaining consistent airflow and static pressure across the system regardless of how many zones are open at a given time. It is appropriate for both residential multi-zone systems and light commercial split or packaged systems with zoning controls.

Key Features

• Heavy-duty construction rated for continuous cycling in zoned system applications
• Integrated motor eliminates need for a separate actuator purchase
• 26 by 16 inch nominal duct opening fits standard trunk and bypass duct configurations
• Motorized operation provides automatic response to zone controller output signals
• Package dimensions of 18 inches wide by 32 inches tall by 8 inches deep allow for standard freight and jobsite handling

Compatibility

Designed as an OEM-style motorized bypass damper for forced-air zoned HVAC systems requiring a 26 by 16 inch bypass damper installation.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with local mechanical codes and the system manufacturer's zoning guidelines. Shut down the air handler and de-energize the zone control panel before beginning any ductwork or wiring connections. Ensure the bypass duct is properly sized and that the damper is oriented according to the airflow direction marked on the unit. Do not operate the system without confirming all low-voltage control wiring connections are secure and correct.
