Air Flow Products 84DB205 Duct Board Tab Takeoff 5 in

Product Description

The AIR FLOW PRODUCTS 84DB205 is a duct board tab takeoff fitting with an integrated damper, designed for use in fibrous glass duct board HVAC distribution systems. The 5-inch round collar allows branch runs to be tapped directly off a main duct board trunk, while the built-in damper provides airflow balancing at the point of takeoff. This fitting is installed by HVAC technicians during new construction or retrofit ductwork fabrication where duct board trunks serve residential or light commercial supply air distribution.

The 84DB205 is suited for duct board applications where field-fabricated fibrous glass trunk lines require branch tap connections. The tab-style construction is designed to seat and adhere to the surface of a duct board trunk, making it a standard component in duct board system layouts. The integral damper allows the installer to regulate airflow to individual zones or rooms without requiring a separate balancing damper downstream.

Key Features

• 5-inch collar diameter for branch duct connections off duct board trunk lines
• Integrated damper allows airflow balancing at the takeoff point
• Tab-style design seats directly onto fibrous glass duct board surface
• Eliminates the need for a separate downstream balancing damper
• Suitable for residential and light commercial supply air distribution systems

Compatibility

Designed as an OEM-style replacement and standard supply fitting for fibrous glass duct board HVAC distribution systems requiring 5-inch branch takeoff connections.

Installation Notes

This fitting is installed by licensed HVAC technicians as part of duct board system fabrication or repair. The air handling system and all associated electrical disconnect switches should be de-energized before beginning ductwork modifications. Tab connections to duct board should be secured and sealed with approved duct board adhesive and foil tape per SMACNA duct board fabrication standards. Do not compress or damage the duct board surface during fitting installation.
