Io Hvac Controls EB-1410 Motorized Bypass Damper 14x10

Product Description

The IO HVAC CONTROLS EB-1410 is a heavy-duty motorized bypass damper designed to regulate airflow in zoned HVAC systems. It opens and closes automatically to divert excess supply air back to the return side of the system, protecting the blower and ductwork from over-pressurization. Built for demanding installations, this damper is suited for residential and light commercial ducted forced-air systems. Licensed HVAC technicians install this component as part of a zoning package to maintain balanced static pressure across the duct network when individual zone dampers close.

The EB-1410 fits a 14 x 10 inch duct opening and is intended for bypass applications in multi-zone systems where pressure relief is required. It is typically installed in a bypass duct that connects the supply plenum to the return plenum. The motorized actuator responds to a signal from the zone control panel, opening the damper when system pressure rises above the design threshold. This unit is appropriate for new construction and retrofit installations in residential and light commercial forced-air systems.

Key Features

• Motorized actuator provides automatic pressure-relief bypass operation in zoned HVAC systems
• Heavy-duty construction supports reliable long-term performance in continuous-duty applications
• 14 x 10 inch duct opening accommodates common residential and light commercial bypass duct sizes
• Compact depth of 8 inches suits tight mechanical room and plenum installations
• Designed for integration with standard zone control panels and low-voltage control wiring

Compatibility

Designed as an OEM-style replacement or new-install motorized bypass damper for residential and light commercial forced-air zoning systems requiring a 14 x 10 inch bypass duct opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems and low-voltage control wiring. Shut down the air handler or furnace and de-energize the zone control panel before making any electrical or duct connections. Follow local mechanical codes and the zone control manufacturer wiring diagram when connecting the actuator leads to the control board. Ensure the bypass duct is properly sealed at all joints to prevent conditioned air loss.
