Io Hvac Controls TD-1608-BM Rectangular Zone Damper 16x8

Product Description

The IO HVAC CONTROLS TD-1608-BM is a rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. Built to fit 16 x 8 inch duct openings, it ships with a Belimo 3-wire actuator mounted at the bottom of the damper body. The actuator operates on a 60-second cycle time, providing controlled airflow regulation across individual zones. This unit is engineered as a direct-fit replacement for Trane and American Standard zoning applications, making it a practical choice for HVAC technicians servicing those systems. The combination of a factory-mounted actuator and a purpose-built damper body reduces field assembly time during installation.

This zone damper is suited for residential and light commercial forced-air zoning installations where Trane or American Standard zone control panels are used. It fits into rectangular duct runs at the 16 x 8 inch duct size and is appropriate for both new zone system builds and retrofit replacements. The bottom-mount actuator orientation is designed to accommodate typical installation clearances found in trunk-and-branch duct layouts. HVAC technicians performing zone system commissioning or replacing failed damper assemblies will find this a direct-swap candidate in compatible systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the zone control panel and any associated low-voltage wiring before connecting the actuator leads. Verify duct opening dimensions before installation to confirm a proper fit. Follow all applicable mechanical and electrical codes, including NEC requirements for low-voltage control wiring.
