Air Flow Products 84ATD05 Stick-on Takeoff Damper 5 in

Product Description

The AIR FLOW PRODUCTS 84ATD05 is an airtight stick-on takeoff fitting with an integrated damper, designed for use with flat duct systems. This fitting allows an HVAC technician to branch airflow from a flat trunk duct to a branch run without cutting into the main duct casing. The airtight construction minimizes air leakage at the takeoff point, supporting system efficiency and helping installations meet energy code requirements. The built-in damper allows for manual airflow balancing at the branch. The 5-inch size suits common residential branch duct runs.

This takeoff is suited for residential and light commercial forced-air HVAC systems that use flat or rectangular trunk duct. It is typically installed during new construction or duct renovation work where branch runs need to be tapped off a flat duct main. The stick-on design simplifies installation by eliminating the need to cut a collar hole in the main duct body, making it a practical choice for retrofit and tight-space applications.

Key Features

• Airtight construction reduces air leakage at the branch takeoff point
• Integrated damper allows airflow balancing at the branch without a separate component
• Stick-on design eliminates the need to cut into the flat duct main
• 5-inch outlet size fits standard residential branch duct runs
• Designed specifically for flat duct configurations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for residential and light commercial flat duct HVAC systems requiring a 5-inch branch takeoff.

Installation Notes

Installation is performed by a licensed HVAC technician. Power down the air handling unit and close the system disconnect before working on any duct section. The stick-on surface should be applied to a clean, dry flat duct face for a secure, airtight seal; follow applicable energy codes such as IECC requirements for duct sealing and leakage. Verify damper operation and set blade position for proper airflow balance after installation.
