Io Hvac Controls CD-3008 Rectangular Zone Damper 30x8

Product Description

The IO HVAC CONTROLS CD-3008 is a rectangular zone damper designed for use in residential and light commercial zoned HVAC systems. It ships with a Belimo 3-wire actuator, giving installers a ready-to-wire, spring-return-capable assembly without sourcing a separate actuator. The damper controls airflow through a specific zone of a ducted forced-air system, opening and closing on a signal from a zone control board or thermostat. At 9 pounds, the unit is substantial enough for reliable duct sealing while remaining manageable for a single-tech install. Licensed HVAC technicians are the primary installer for this type of component.

This damper is sized for a 30-by-8-inch duct opening and is intended as a direct replacement for Carrier and Bryant rectangular zone dampers in existing zoned systems. Typical applications include residential multi-zone split systems and light commercial forced-air installations where individual rooms or areas require independent temperature control. The included Belimo 3-wire actuator is compatible with standard zone control panel outputs, making this a drop-in upgrade or service replacement for failed OEM dampers in Carrier and Bryant equipment.

Key Features

• Sized for 30-by-8-inch rectangular duct openings
• Includes Belimo 3-wire actuator - no separate actuator purchase required
• Designed as a Carrier and Bryant OEM-style replacement
• Spring-return actuator design supports fail-safe damper positioning on power loss
• Ready-to-install assembly reduces field assembly time

Compatibility

Designed as a direct replacement for Carrier and Bryant rectangular zone dampers in ducted forced-air zoning systems with 30-by-8-inch duct openings.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control panel before removing the existing damper or disconnecting actuator wiring. The 3-wire actuator connects to the zone control board per the board manufacturer's wiring diagram - verify control voltage compatibility before energizing. Follow applicable local mechanical codes and manufacturer instructions for duct sealing around the damper frame.
