Io Hvac Controls TD-2408-BM Rectangular Zone Damper 24x8

Product Description

The IO HVAC CONTROLS TD-2408-BM is a rectangular zone damper designed for use in residential and light commercial zoning systems. It features a bottom-mount Belimo 3-wire actuator with a 60-second drive time, giving HVAC technicians reliable, repeatable airflow control across independently conditioned zones. The damper measures 24 inches wide by 8 inches in duct opening size and ships at 9 pounds. Zone dampers of this type are installed by licensed HVAC technicians as part of a multi-zone forced-air system, working in conjunction with a zone control panel and a bypass damper to manage static pressure across variable air volume conditions.

This damper is built as a direct-fit replacement for Trane and American Standard zoning applications that specify a 24x8 inch rectangular zone damper with a bottom-mount actuator configuration. It is suited for residential forced-air duct systems where individual zones require independent temperature control. The 3-wire Belimo actuator is compatible with standard 24-volt zone control boards used in split-system and heat pump installations. Contractors working on Trane or American Standard zone systems will find this damper sized and configured to match OEM layout requirements without modification.

Key Features

• 24x8 inch rectangular duct opening for direct OEM-style replacement in Trane and American Standard zone systems
• Bottom-mount Belimo 3-wire actuator for reliable zone-by-zone airflow control
• 60-second actuator drive time for smooth, controlled damper operation
• 24-volt actuator signal compatible with standard residential zone control panels
• Ships ready to install with actuator pre-mounted at the bottom position

Compatibility

Designed as a direct-fit replacement for Trane and American Standard rectangular zone damper applications requiring a 24x8 inch bottom-mount actuator configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician. De-energize the zone control panel and disconnect all low-voltage wiring before removing the existing damper. Verify duct opening dimensions and actuator mounting orientation before securing the damper in place. Follow all applicable mechanical and electrical codes, including NEC requirements for low-voltage control wiring.
