Io Hvac Controls ZD-3616-BM Zone Damper 36x16 Bottom Mount

Product Description

The IO HVAC CONTROLS ZD-3616-BM is a modulating commercial zone damper designed to control airflow in multi-zone HVAC ducting systems. Built for commercial-grade applications, this bottom-mount damper fits a 36 x 16 inch duct opening and provides precise, variable airflow regulation rather than simple open/close operation. Its modulating design allows the actuator to position the damper blade at any point across the full range of travel, giving building automation and zone control systems the proportional control they require. Licensed HVAC technicians and commercial mechanical contractors handle installation and commissioning of this type of equipment.

This damper is suited for commercial and light-industrial HVAC installations where zoned air distribution is required. The bottom-mount configuration is used when actuator access from below the duct is the preferred or required installation orientation. Typical applications include VAV-style zone control in commercial buildings, warehouses, offices, and other facilities where multiple independently controlled zones share a common air-handling system. It is sized for a 36 x 16 inch duct collar and is intended for use with a compatible modulating actuator, which is sourced separately.

Key Features

• Modulating operation enables proportional airflow control across the full blade-travel range
• Bottom-mount actuator position suits installations where top or side access is restricted
• Sized for 36 x 16 inch duct openings - commercial duct dimensions
• Packaged dimensions of 22 inches wide, 38 inches tall, and 7 inches deep for shipping and storage planning
• 15-pound unit weight indicating heavy-duty commercial construction

Compatibility

Designed as an OEM-style modulating zone damper for commercial ducted HVAC systems requiring proportional airflow control in a 36 x 16 inch duct application.

Installation Notes

Installation of commercial zone dampers should be performed by a licensed HVAC contractor or journeyman technician familiar with commercial air distribution systems. Disconnect and lock out power to the air-handling unit and any associated control panels before beginning installation. The modulating actuator must be matched to the damper shaft and control signal type specified by the zone control system - do not force or over-travel the actuator beyond the damper blade limits. Follow local mechanical codes and manufacturer wiring guidelines when connecting the actuator control wiring to the building automation or zone controller.
