Air Flow Products 850-1-000000-001410 Reducer Increaser 14x10

Product Description

The AIR FLOW PRODUCTS 850-1-000000-001410 is a Series 85 reducer/increaser designed for HVAC duct transitions. This fitting connects duct sections of different sizes, stepping down from a 14-inch opening to a 10-inch opening or stepping up in the reverse direction. It is sold as a single unit and is intended for use by licensed HVAC technicians and sheet metal contractors working on residential or light commercial forced-air systems. The Series 85 designation identifies its product line within the Air Flow Products catalog, confirming OEM-style fitment for standard rectangular duct configurations.

This reducer/increaser is used wherever a duct run changes cross-sectional size, such as at the transition from a main trunk to a branch run, or where system layout requires upsizing or downsizing the airflow path. The 14 x 10 inch sizing makes it a common fit in residential forced-air installations where trunk-to-branch transitions are frequent. HVAC installers and service technicians use fittings like this during new construction, duct replacement, or system modification work.

Installation Notes

Installation should be performed by a qualified HVAC technician or licensed sheet metal contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handler and confirm the system is de-energized before working on the duct section. Secure the fitting using appropriate sheet metal screws and seal all joints with UL 181-rated mastic or foil tape to maintain system pressure and efficiency. Do not substitute sealant types not rated for HVAC duct applications.
