Io Hvac Controls LD-1806-BM Zone Damper 18x6 2 Position

Product Description

The IO HVAC CONTROLS LD-1806-BM is an 18 x 6 inch rectangular 2-position zone damper designed for use in ducted HVAC zoning systems. Fitted with a 3-wire actuator and an LED status indicator, the damper provides straightforward open/close control of airflow through a zone. The bottom-mount actuator configuration allows installation in applications where side access is limited. This unit is installed by licensed HVAC technicians as part of a zoned forced-air system, giving each zone independent temperature control and improving overall system efficiency.

This damper is suited for residential and light commercial duct systems where zone-by-zone airflow management is required. The rectangular duct configuration fits standard 18 x 6 inch duct runs. The 2-position operation keeps controls simple: the actuator drives the blade fully open or fully closed based on a signal from a compatible zone control panel. The LED indicator provides quick visual confirmation of damper status during commissioning or service calls, reducing troubleshooting time at the unit.

Key Features

• 2-position operation: fully open or fully closed for straightforward zone control
• 3-wire actuator for compatibility with standard zone control panels
• LED status indicator for quick visual confirmation during install and service
• Bottom-mount actuator design for installations with limited side clearance
• Rectangular form factor fits standard 18 x 6 inch duct openings

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC systems requiring 2-position control in an 18 x 6 inch duct opening.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler and zone control panel before making any wiring connections to the actuator. Verify duct dimensions and mounting orientation before securing the damper in the duct opening. Confirm proper actuator response and LED status after wiring is complete and power is restored.
