Io Hvac Controls ld-1208-bm Zone Damper 12x8 in 2 Position

Product Description

The IO HVAC CONTROLS ld-1208-bm is a rectangular, 2-position zone damper designed for residential HVAC zoning systems. Measuring 12 inches by 8 inches, it uses a 3-wire actuator with an integrated LED indicator for fast visual confirmation of damper position. The bottom-mount configuration allows for straightforward installation in duct runs where access is limited to the underside of the ductwork. Licensed HVAC technicians install this type of damper as part of zone control systems that regulate airflow to individual areas of a home.

This damper is suited for residential forced-air zoning applications where independent temperature control is required across multiple zones. Its rectangular profile fits standard rectangular duct sizes, making it a practical choice for retrofit and new-construction residential zoning projects. The 2-position operation means the damper moves fully open or fully closed on a control signal, which is standard practice in most residential zone control setups.

Key Features

• 12 inches by 8 inches rectangular duct size for standard residential ductwork
• 2-position operation for fully open or fully closed airflow control
• 3-wire actuator for compatibility with typical zone control boards
• Integrated LED indicator for quick visual confirmation of actuator position
• Bottom-mount design for installations where underside access is required

Compatibility

Designed as an OEM-style replacement or new-install zone damper for residential rectangular duct zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with residential zoning systems. Power down the air handler and zone control panel before wiring the actuator. Follow the zone control board manufacturer's wiring diagram for 3-wire actuator connections. Ensure the damper is mounted securely to the duct with sheet metal screws and that all duct connections are properly sealed after installation.
