Io Hvac Controls sd-1812 Zone Damper 18x12 Inches

Product Description

The IO HVAC CONTROLS sd-1812 is a rectangular auxiliary zone damper sized at 18 inches by 12 inches, designed for use in commercial HVAC zoning systems. Zone dampers control airflow to individual zones within a ducted forced-air system, allowing independent temperature management across multiple areas. The sd-1812 fits into rectangular ductwork and is actuated as part of a zoning control setup. Licensed HVAC technicians typically specify and install this component during new zoning installations or when replacing a failed auxiliary damper in an existing multi-zone system.

The sd-1812 is rated for commercial HVAC applications where rectangular zone dampers are required. Its 18-inch by 12-inch face size suits medium to large duct runs commonly found in light commercial and larger residential zoning layouts. This damper functions as an auxiliary unit, meaning it operates in conjunction with a primary zone control panel and thermostat network to regulate conditioned airflow room by room or zone by zone.

Key Features

• Rectangular form factor fits standard 18-inch by 12-inch duct openings
• Auxiliary zone damper configuration for use with multi-zone HVAC control systems
• Rated for commercial HVAC application environments
• Designed as a direct-fit component for zoning airflow control in ducted systems

Compatibility

Designed as an OEM-style auxiliary zone damper replacement or new installation component for commercial rectangular ductwork systems requiring an 18-inch by 12-inch damper.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoning system wiring and ductwork modifications. Power down the air handler and zone control panel before installing or replacing the damper. Secure the damper into the duct opening according to the manufacturer instructions and verify actuator wiring is connected to the correct zone output on the control board before restoring power. Follow local mechanical codes and manufacturer guidelines for duct sealing around the damper frame.
