Io Hvac Controls EB-1008 Motorized Bypass Damper 10x8

Product Description

The IO HVAC CONTROLS EB-1008 is a heavy-duty motorized bypass damper designed to regulate airflow in zoned HVAC duct systems. When zone dampers close and static pressure rises in the supply duct, a bypass damper redirects excess air back to the return side, protecting the air handler and maintaining balanced system pressure. The EB-1008 fits a 10-inch by 8-inch duct opening and ships at 7 pounds, indicating a robust metal construction suited for commercial and residential applications. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system to prevent over-pressurization and blower strain.

This motorized bypass damper is used in residential and light commercial forced-air zoning applications where two or more zone dampers are controlled by a zone control panel. It mounts inline in the duct system between the supply plenum and the return plenum, opening automatically as zone demand drops and supply pressure increases. It is appropriate for new construction zoning installations as well as retrofit zoning upgrades on existing ductwork.

Key Features

• Heavy-duty construction rated for continuous bypass duty in zoned forced-air systems
• Motorized actuator opens and closes the damper blade automatically in response to system pressure or zone control signals
• 10-inch by 8-inch duct opening fits standard rectangular duct sizing
• Compact depth of 8 inches suits tight mechanical room and plenum installations
• Shipping weight of 7 pounds reflects durable metal damper body and actuator assembly

Compatibility

Designed as an OEM-style motorized bypass damper for use with residential and light commercial zoned forced-air HVAC systems requiring a 10-inch by 8-inch bypass duct connection.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes. Power down the air handler and zone control panel before making any wiring connections to the damper actuator. The damper must be mounted with proper duct transitions to ensure an airtight seal and correct airflow direction as indicated on the damper housing. Low-voltage control wiring should be run and connected per the zone controller manufacturer's wiring diagram.
