Air Flow Products 84ATD-2-12 Stick-on Takeoff Damper 12 in

Product Description

The AIR FLOW PRODUCTS 84ATD-2-12 is an airtight stick-on takeoff with an integrated damper designed for use with flat duct systems. This fitting allows HVAC technicians to branch supply air from a flat duct run without cutting into the main trunk — the adhesive-backed collar bonds directly to the duct surface for a secure, airtight seal. The built-in damper provides on-the-spot airflow control at the branch point, making it a practical choice for zoning adjustments and balancing during installation or service. This 12-inch unit is sized for standard residential and light commercial flat duct applications.

This takeoff is suited for residential and light commercial HVAC duct systems where flat duct is the primary distribution method. It is typically installed by HVAC technicians during new construction duct runs or retrofit work where adding a branch takeoff is required without full duct modification. The integrated damper simplifies airflow balancing at the branch level, reducing the need for separate damper hardware.

Key Features

• Airtight adhesive-backed collar bonds directly to flat duct surface without cutting the main trunk
• Integrated damper allows airflow adjustment at the takeoff point
• 12-inch size suits standard residential and light commercial flat duct installations
• Stick-on design reduces installation time compared to conventional screw-in or welded takeoffs
• Designed to minimize air leakage at the branch connection point

Compatibility

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

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power down the air handler or furnace and ensure the system is not pressurized before attaching the takeoff. Clean and dry the flat duct surface thoroughly before applying the adhesive collar to ensure a proper airtight bond. Follow local mechanical codes and ACCA Manual D guidelines for duct branch sizing and airflow balancing.
