Air Flow Products RE087 Reducer Increaser 8 to 7 Inch

Product Description

The AIR FLOW PRODUCTS RE087 is a duct reducer-increaser fitting designed to transition between an 8-inch and a 7-inch round duct section. This type of fitting is used to connect two duct runs of different diameters, maintaining airflow continuity through the transition. It is a standard sheet metal duct component installed in residential and light commercial HVAC ductwork systems. HVAC technicians and sheet metal installers select this fitting when a duct run changes diameter, whether reducing from a larger trunk or stepping up to match a branch connection.

The RE087 fits into typical forced-air duct systems where transitions between round duct sizes are required. Common scenarios include connecting a main supply trunk to a smaller branch run, adapting an air handler outlet to a downstream duct section, or reconfiguring ductwork during a system replacement or renovation. This fitting is suited for both new construction and retrofit installations where a clean, secure 8-to-7 inch round duct transition is needed.

Key Features

• Transitions between 8-inch and 7-inch round duct diameters
• Standard reducer-increaser profile for low-resistance airflow transition
• Compatible with round duct fittings and connections standard to the trade
• Suitable for supply and return air duct applications in forced-air systems

Compatibility

Designed as an OEM-style replacement and new-construction fitting for 8-inch to 7-inch round duct systems in residential and light commercial forced-air HVAC installations.

Installation Notes

Installation should be performed by a qualified HVAC technician or sheet metal installer in accordance with local mechanical codes and SMACNA duct construction standards. Power the air handling unit off before working inside an active duct system. Secure the fitting with sheet metal screws and seal all joints with listed duct sealant or UL 181-rated foil tape to prevent air leakage. Do not leave unsealed joints in conditioned or pressurized duct sections.
