Io Hvac Controls sd-2814 Zone Damper 28x14 Inches

Product Description

The IO HVAC CONTROLS sd-2814 is a rectangular auxiliary zone damper designed for use in commercial HVAC zoning systems. Measuring 28 inches by 14 inches, it controls airflow through individual zones by opening and closing on signal from a zone control panel or thermostat. Licensed HVAC technicians and mechanical contractors install this damper as part of a multi-zone forced-air system to balance airflow and meet the heating and cooling demands of separate spaces. Its rectangular profile fits standard commercial ductwork of the same nominal dimensions.

This damper is suited for commercial HVAC applications where multiple zones must be independently controlled. It is typically installed in supply or return duct branches serving distinct occupied areas such as offices, retail spaces, or multi-room commercial buildings. The auxiliary designation indicates it serves secondary zones within a broader zoning layout, supplementing a primary zone control architecture. Proper placement in the duct system is determined during the zoning design phase before installation begins.

Key Features

• Rectangular form factor fits 28-inch by 14-inch commercial duct openings
• Auxiliary zone configuration supports multi-zone HVAC system layouts
• Designed for commercial-grade forced-air zoning applications
• Compatible with zone control panels and low-voltage thermostat wiring

Compatibility

Designed as an OEM-style auxiliary zone damper for commercial rectangular duct systems requiring 28-inch by 14-inch damper installation in forced-air zoning applications.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and local mechanical codes. De-energize the air handler and zone control panel before beginning work in the duct system. Secure the damper in the duct with sheet metal screws and seal all joints with approved duct sealant or foil tape. Connect the actuator wiring to the zone panel per the panel manufacturer's low-voltage wiring diagram.
