Io Hvac Controls ZD-1008-BM Zone Damper 10x8 Bottom Mount

Product Description

The IO HVAC CONTROLS ZD-1008-BM is a modulating commercial zone damper designed for precise airflow control in multi-zone HVAC systems. Built for 10-inch by 8-inch duct openings and configured for bottom mount installation, this damper provides proportional positioning rather than simple open/close operation, allowing the system controller to modulate airflow to match zone demand. At 7 pounds, the unit is sized for commercial applications where residential-grade dampers are not appropriate. Licensed HVAC technicians and commercial mechanical contractors are the primary installers of this equipment.

This damper is suited for commercial and light-industrial forced-air systems that require zoned airflow management. The bottom mount configuration fits specific plenum and duct layouts where top or side access is not available. It is appropriate for new construction mechanical rooms as well as retrofit zoning projects in existing commercial buildings. The modulating action makes it compatible with variable-output zone controllers and building automation systems that output an analog or proportional control signal.

Key Features

• Modulating operation for proportional airflow control, not limited to open/close positions
• Fits 10-inch by 8-inch duct openings
• Bottom mount configuration for specific plenum and duct access layouts
• Commercial-grade construction suitable for multi-zone forced-air systems
• 7-pound unit weight indicating robust build for commercial service environments

Compatibility

Designed as an OEM-style replacement or new-installation modulating zone damper for commercial multi-zone forced-air HVAC systems requiring a 10-inch by 8-inch bottom mount damper assembly.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and applicable mechanical codes. Shut down the air handling unit and de-energize all associated control wiring before beginning installation or wiring connections. Verify that the control signal type from the zone controller matches the damper actuator input requirements before completing the low-voltage wiring. Secure the damper to the duct or plenum per the manufacturer mounting instructions and confirm full range of motion before restoring system power.
