Durozone 35047 Round Motorized Duct Damper 14 Inches

Product Description

The DUROZONE 35047 is a round, motorized, single-blade duct damper designed for precise airflow control in forced-air HVAC distribution systems. Built from galvanized steel, the 35047 ships with a motor included and features a crimped edge that creates a true-size fit inside standard round ductwork. The single-blade design delivers smooth actuation and efficient sealing, reducing air bypass and maintaining zone pressure balance. HVAC technicians install this damper as part of zoning systems where independent room or area control is required.

The 35047 is suited for residential and light commercial forced-air zoning applications. The round housing is compatible with flexible ducting and round sheet metal duct, making it a practical choice for both new construction and retrofit installations. The 14-inch diameter fits standard round duct of that size without modification. A single set screw secures the motor to the damper body, simplifying field installation and reducing the chance of motor slippage during operation.

Key Features

• 14-inch diameter round housing fits standard flexible or sheet metal round duct
• Galvanized steel blade construction for corrosion resistance in air distribution environments
• Motor included — no separate actuator purchase required
• Crimped edge design ensures true-size fit and minimal air bypass
• Single set screw motor retention simplifies field installation
• Single-blade design provides smooth operation and efficient sealing

Compatibility

Designed as an OEM-style replacement or new-installation damper for 14-inch round duct in residential and light commercial forced-air zoning systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician as part of a zoned forced-air system. Power down the air handler and any associated zone controllers before wiring the damper motor. Secure the damper in-line with round ductwork using sheet metal screws or approved duct tape per local mechanical code requirements. Verify motor wiring connections against the zone controller specifications before restoring power.
