Description
HVAC-SH Air Reducer (Duct Reducer)
Product Overview
The HVAC-SH Air Reducer, also known as a Duct Reducer, is designed to connect ducts of different diameters or cross-sectional sizes within HVAC systems.
It ensures smooth airflow transition, minimizes turbulence, and reduces pressure loss when changing duct sizes.
This component is widely used in air supply, return, and exhaust systems for commercial and industrial HVAC applications.
