Io Hvac Controls ZD-05 Modulating Zone Damper 5in

Product Description

The IO HVAC CONTROLS ZD-05 is a 5-inch modulating zone damper designed for commercial HVAC zoning systems. It controls airflow within a duct network by adjusting blade position across a range of positions, rather than simply opening or closing. This modulating action allows the system to deliver precise airflow to individual zones based on demand. The unit measures 5 inches wide, 5 inches high, and 8 inches deep, and weighs 4 pounds. It is typically installed by licensed HVAC technicians as part of a multi-zone forced-air system.

The ZD-05 is suited for commercial zoning applications where variable airflow control is required across multiple duct branches. Modulating dampers are commonly used in variable air volume (VAV) setups and multi-zone systems where a zone controller or building automation system sends a modulating signal to adjust damper position. This damper fits inline within a 5-inch round or equivalent duct run and is appropriate for light commercial installations requiring more than simple open/close operation.

Key Features

• Modulating operation for precise, variable airflow control across zones
• 5-inch duct size suits common commercial branch duct configurations
• Compact form factor at 5 inches wide by 5 inches high by 8 inches deep
• Lightweight at 4 pounds for straightforward in-duct installation
• Designed for integration with zone controllers or building automation systems

Compatibility

Designed as an OEM-style modulating zone damper for use in commercial forced-air HVAC zoning systems requiring a 5-inch duct connection.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down and lock out the air handling unit before installing or wiring the damper. Secure the damper inline with the duct run per the manufacturer instructions and ensure all low-voltage control wiring connections are made according to the zone controller wiring diagram. Reference applicable mechanical codes for duct penetration and support requirements.
