Io Hvac Controls ZD-2008 Modulating Zone Damper 20x8

Product Description

The IO HVAC CONTROLS ZD-2008 is a modulating commercial zone damper designed to regulate airflow in multi-zone HVAC duct systems. Measuring 20 inches wide by 8 inches tall with a 6-inch depth, this damper accepts variable positioning signals to precisely control the volume of conditioned air delivered to individual zones. It is installed by licensed HVAC technicians in commercial zoning applications where proportional airflow control is required, rather than simple open/close operation. At 8 pounds, the unit is substantial enough for commercial ductwork while remaining manageable for single-technician installation.

The ZD-2008 is suited for commercial and light-industrial HVAC zoning systems where individual zones require independent airflow modulation. Typical installations include multi-zone rooftop unit applications, variable air volume (VAV) systems, and commercial forced-air builds requiring duct-level zone control. The damper fits rectangular duct openings sized at 20 inches by 8 inches, making it appropriate for medium-capacity trunk or branch duct runs in commercial construction.

Key Features

• Modulating operation allows proportional airflow control beyond simple open/close positioning
• Commercial-grade construction sized for 20-inch by 8-inch rectangular duct openings
• 6-inch depth accommodates standard duct collar and actuator clearance requirements
• 8-pound unit weight supports single-technician overhead or in-duct installation
• Designed for multi-zone commercial HVAC applications requiring zone-level airflow regulation

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular duct systems with a 20-inch by 8-inch opening.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes and the equipment manufacturer's instructions. Shut down and lock out the HVAC system before inserting or securing the damper in the duct opening. Verify actuator signal type and control wiring compatibility with the zone controller before making electrical connections. Confirm the duct opening dimensions match the damper face size before installation to ensure a proper seal.
