Air Flow Products 84ATD12 Stick-on Takeoff Damper 12 in

Product Description

The AIR FLOW PRODUCTS 84ATD12 is an airtight stick-on takeoff fitting with an integral damper, designed for use with flat duct systems. It provides a sealed branch connection point that allows airflow to be directed from a main flat duct run into a branch line, with the built-in damper enabling flow adjustment at the takeoff point. The airtight construction minimizes duct leakage, supporting system efficiency in forced-air HVAC applications. The 12-inch size suits a range of residential and light commercial duct configurations. Licensed HVAC technicians and sheet metal installers are the primary users of this fitting.

This takeoff is intended for flat duct installations in forced-air heating and cooling systems. The stick-on design allows the fitting to be applied directly to the flat duct surface, simplifying branch connections during new installations or retrofits. It is appropriate for residential and light commercial applications where airtight duct construction is required to meet energy codes or system performance targets. The built-in damper allows the installer to balance airflow at each branch without adding a separate damper component.

Key Features

• Airtight construction reduces duct leakage at branch takeoff points
• Integral damper allows airflow balancing at the point of connection
• Stick-on installation method simplifies attachment to flat duct surfaces
• 12-inch size suits a range of residential and light commercial duct branch applications
• Designed for flat duct systems, compatible with common forced-air HVAC configurations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for flat duct systems in residential and light commercial forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal installer. Power down the air handler or furnace and close the system before making duct modifications. Ensure the flat duct surface is clean and free of debris before applying the stick-on fitting to achieve a proper airtight seal. Follow local mechanical codes and SMACNA duct construction standards for branch takeoff installation and airflow balancing procedures.
