Io Hvac Controls ZD-1408 Modulating Zone Damper 14x8

Product Description

The IO HVAC CONTROLS ZD-1408 is a modulating zone damper designed for commercial HVAC zoning applications. It controls airflow within a duct system by adjusting blade position across a continuous range of travel, not just open or closed. This allows precise zone-by-zone temperature management in multi-zone forced-air systems. The damper ships at 7 pounds and fits a 14 by 8 inch duct opening. Licensed HVAC technicians and commercial mechanical contractors are the primary installers of this component.

This damper is suited for commercial zoning systems where modulating control is required, as opposed to two-position dampers used in simpler residential setups. Typical installations include rooftop unit zoning, air handler distribution systems, and VAV-style commercial builds where zone controllers or thermostats signal the actuator to modulate airflow based on demand. It is not a residential bypass or balancing damper.

Key Features

• Modulating operation for continuous airflow adjustment across full stroke range
• Commercial-grade construction rated for higher duty cycles than residential zone dampers
• 14 by 8 inch duct collar fitment for standard rectangular duct sections
• Compact packaged dimensions of 10 inches wide by 25 inches tall by 9 inches deep for straightforward duct integration
• Ships at 7 pounds for manageable single-technician handling during overhead or wall-cavity installs

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular duct systems requiring a 14 by 8 inch opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning controls and low-voltage control wiring. De-energize the air handler or rooftop unit and set the zone controller to a safe state before installing or wiring the damper actuator. Secure the damper collar to the duct using sheet metal screws and appropriate duct sealant per local mechanical code. Verify actuator control signal type and wiring polarity against the zone controller documentation before powering the system.
