Air Flow Products 84ATD-2-14 Flat Duct Takeoff with Damper

Product Description

The Air Flow Products 84ATD-2-14 is an airtight stick-on takeoff fitting with an integrated damper, designed for use with flat duct systems. This fitting allows HVAC technicians to tap off a flat duct run and control airflow through the branch with the built-in damper. The airtight construction minimizes air leakage at the takeoff point, helping maintain system efficiency and consistent pressure balance across the distribution network. At 14 inches, it suits branch runs common in residential and light commercial forced-air applications. Installation is handled by qualified HVAC technicians during duct fabrication or retrofit work.

This takeoff is suited for residential and light commercial HVAC duct systems where flat duct is used as the primary supply or return distribution method. The stick-on design allows the fitting to be applied directly to the flat duct surface without the need for additional flanges or mounting hardware beyond the adhesive seal. The integral damper provides adjustable airflow regulation at the branch point, making it useful in zoning applications or balancing multi-branch duct systems.

Key Features

• Airtight construction reduces air leakage at the takeoff connection
• Stick-on design simplifies installation on flat duct surfaces
• Integrated damper allows branch airflow regulation and system balancing
• 14-inch size accommodates standard branch duct runs in residential and light commercial systems
• Designed specifically for flat duct applications

Compatibility

Designed as an OEM-style replacement and new-installation fitting for flat duct HVAC distribution systems requiring airtight branch takeoff connections with damper control.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handling unit and relieve system pressure before cutting into any existing duct. Ensure the flat duct surface is clean and free of debris before applying the stick-on fitting to achieve a proper airtight seal. Follow applicable local mechanical codes and SMACNA duct construction standards during installation.
