Io Hvac Controls EB-1008-BM Motorized Bypass Damper 10x8

Product Description

The IO HVAC CONTROLS EB-1008-BM is a heavy-duty motorized bypass damper designed to regulate airflow in forced-air HVAC systems. It mounts to the bottom of a plenum or ductwork section and uses an integrated motor to open and close the bypass blade, diverting excess static pressure away from the main supply trunk. The damper measures 10 x 8 inches at the duct opening and ships at 5.76 pounds, making it a manageable single-technician install. Licensed HVAC technicians typically specify this component in zoning applications where variable air volume control is required.

This damper is suited for residential and light-commercial forced-air zoning systems. The bottom-mounted actuator configuration makes it appropriate for applications where top or side access is restricted. It is installed in the supply or bypass duct run between the air handler and the zone damper network, allowing the system to shed pressure when one or more zones close. Installers working on multi-zone systems with ECM or PSC air handlers commonly use this style of bypass damper to protect the blower from excess static pressure.

Key Features

• Heavy-duty construction rated for continuous cycling in zoning applications
• Integrated motorized actuator factory-mounted to the bottom of the damper body
• 10 x 8 inch duct opening fits standard rectangular duct sizes
• Bottom-mounted design provides clearance where top or side access is limited
• Compact overall footprint: 13 inches wide, 13 inches tall, 7 inches deep

Compatibility

Designed as an OEM-style replacement or new-installation bypass damper for rectangular duct zoning systems requiring a bottom-mounted motorized actuator configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Disconnect and lock out power to the air handler and zone control panel before beginning any wiring or duct work. Secure the damper to the duct section using sheet metal screws and seal all flanged edges with UL-listed foil tape or mastic. Verify actuator wiring and control voltage connections comply with the zone controller manufacturer specifications and applicable local mechanical codes before restoring power.
