“a type of fitting used in ventilation, HVAC (Heating, Ventilation, and Air Conditioning) systems, and other ductwork installations. Its purpose is to smoothly transition the airflow from a square or rectangular duct to a round duct or vice versa.
In HVAC systems and other industrial applications, ducts often come in various shapes, including square, rectangular, and round. However, in some instances, you may need to change the duct shape to accommodate different equipment or structural requirements. That’s where a square-to-round transition comes into play.
The transition consists of two main parts:
Square Inlet or Outlet: This part of the fitting is designed to connect to the square or rectangular duct. It usually has flanges or other attachment methods for secure connections.
Round Inlet or Outlet: This part of the fitting connects to the round duct. Like the square end, it is also designed for a secure connection.
The transition is carefully designed to ensure that the change in shape does not cause significant turbulence or disruption to the airflow, which could result in pressure drops and reduced system efficiency. Properly designed square-to-round transitions help maintain a smooth and efficient flow of air through the ductwork.
These fittings are available in various sizes to accommodate different duct dimensions and are typically made from sheet metal or other suitable materials used in HVAC and ducting applications. They are commonly used in industrial ventilation systems, commercial buildings, and residential HVAC installations where different duct shapes must be connected together.”
