Io Hvac Controls ld-1808-bm Zone Damper 18x8 in 2 Position

Product Description

The IO HVAC CONTROLS ld-1808-bm is a rectangular, 2-position zone damper designed for residential forced-air HVAC zoning systems. It ships with a 3-wire actuator and an integrated LED indicator, and it mounts from the bottom of the duct opening. The damper moves between fully open and fully closed positions, controlled by a zone panel or thermostat system. HVAC technicians use this damper to divide a single air-handler system into independently controlled zones, improving comfort and reducing energy waste. The LED indicator gives a quick visual confirmation of damper position during setup and troubleshooting.

This damper is sized at 18 inches by 8 inches to fit standard rectangular duct openings of that dimension. It is intended for residential zoning applications where a low-voltage zone control panel drives multiple dampers from a single air handler. The bottom-mount actuator configuration is suited for installations where top or side access is limited. Licensed HVAC technicians typically install this as part of a new zoning system or as a replacement damper in an existing layout.

Key Features

• 2-position operation: fully open or fully closed for reliable zone control
• 3-wire actuator included, compatible with standard low-voltage zone panel wiring
• Integrated LED indicator for fast visual confirmation of damper state
• Bottom-mount actuator design accommodates tight duct installations
• Rectangular form factor fits standard 18 inch by 8 inch duct openings
• Residential application rating for forced-air zoning systems

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct systems requiring a 2-position, 3-wire actuator damper in an 18 inch by 8 inch duct opening.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down and lock out the air-handling unit before mounting the damper or making any wiring connections. Low-voltage wiring to the zone panel must comply with NEC requirements and the zone control manufacturer wiring guidelines. Confirm the actuator rotation direction and blade position before restoring power to the system.
