Io Hvac Controls MBD-2216 Manual Balancing Damper 22x16

Product Description

The IO HVAC CONTROLS MBD-2216 is a manual balancing damper sized at 22 x 16 inches, designed for airflow regulation in ducted HVAC distribution systems. It includes a locking quadrant that allows technicians to set and hold a precise blade position once the desired airflow balance is achieved. Manual balancing dampers like this one are a standard component in residential and light commercial air distribution networks, used to tune individual branch runs and ensure proper airflow across zones. Installation and adjustment are typically performed by licensed HVAC technicians during system commissioning or rebalancing service calls.

The MBD-2216 fits into ductwork applications where a 22 x 16 inch damper is required. It is well suited for main trunk branch takeoffs, air handler supply-side distribution, and multi-zone balancing work in both new construction and retrofit scenarios. The locking quadrant allows the set position to remain fixed after balancing, preventing accidental adjustment during normal system operation.

Key Features

• 22 x 16 inch damper size for standard rectangular duct applications
• Locking quadrant holds blade position after balancing is complete
• Manual operation requires no actuator or control wiring
• Suited for airflow balancing on supply-side duct branches in residential and light commercial systems
• Ships at 12.45 pounds, indicating a robust sheet metal construction

Compatibility

Designed as an OEM-style manual balancing damper for rectangular duct systems requiring a 22 x 16 inch damper opening.

Installation Notes

Installation is performed by a licensed HVAC technician. Power down the air handling unit before cutting into ductwork or securing the damper in place. The damper should be inserted into the duct run and fastened per local mechanical code requirements, then adjusted during a live system airflow test before locking the quadrant. Do not exceed the rated duct velocity for this damper size as specified by the system design engineer.
