Io Hvac Controls LD-2218 Rectangular Zone Damper 22x18

Product Description

The IO HVAC CONTROLS LD-2218 is a rectangular 2-position zone damper designed for HVAC zoning systems in residential and light commercial ductwork. Measuring 22 inches by 18 inches, it uses a 3-wire actuator for reliable open/close control and includes an integrated LED indicator for quick visual confirmation of damper position. Zone dampers like this one are installed by licensed HVAC technicians to divide a forced-air system into independently controlled zones, improving comfort and system efficiency across multi-zone installations.

The LD-2218 is suited for rectangular duct applications where a 22-inch by 18-inch damper footprint is required. It is commonly installed in zoned residential systems and light commercial forced-air setups. The 3-wire actuator configuration is compatible with standard zone control boards and thermostats used in 2-position zoning applications. The LED indicator allows technicians to confirm damper status without removing the unit from the duct.

Key Features

• 22 inch by 18 inch rectangular form factor fits standard duct openings of that dimension
• 2-position operation for straightforward open/close zone control
• 3-wire actuator interfaces with most standard zone control boards
• Integrated LED indicator provides at-a-glance damper position status
• Packaged dimensions of 21 inches wide by 29 inches tall by 9 inches deep for shipping and storage reference

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems requiring a 22 inch by 18 inch 2-position damper with a 3-wire actuator interface.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the zone control board and air handler before installing or replacing the damper. Ensure the duct opening is clear of obstructions and that the actuator wiring is connected according to the zone control board manufacturer's wiring diagram. Follow applicable local mechanical codes and manufacturer guidelines when integrating into an existing zoning system.
