Io Hvac Controls MD-1608 Rectangular Zone Damper 16x8 in

Product Description

The IO HVAC CONTROLS MD-1608 is a rectangular 2-position zone damper sized at 16 inches wide by 8 inches tall, designed for residential and light commercial HVAC zoning systems. It ships with a Belimo 3-wire actuator, providing reliable open/close control for supply air distribution. The 2-position actuator drives the blade fully open or fully closed on a 24-volt signal, making it a straightforward fit for conventional zone control panels. At 7 pounds, the unit is manageable for a single technician to handle during duct installation. HVAC contractors and sheet metal installers are the primary trade professionals who specify and install this damper.

This damper is suited for rectangular duct applications in zoned forced-air systems, both heating and cooling. It fits inline into a duct run where zone-by-zone airflow control is required. Typical installations include residential multi-zone systems controlled by a dedicated zone panel, as well as light commercial applications where individual room or area control is needed. The 16-inch by 8-inch throat size matches standard rectangular duct dimensions commonly found in residential and small commercial construction.

Installation Notes

Installation is performed by licensed HVAC contractors or qualified sheet metal technicians. Power down the zone control panel and air handler before wiring the actuator. Secure the damper body to the duct using sheet metal screws and seal joints with approved duct tape or mastic to prevent air bypass. Follow NEC requirements for low-voltage wiring runs to the actuator.
