Reducers are components that taper down one end of a duct to match the size of the other duct when connecting two ducts of different sizes.

You can purchase several sizes of reducers to fit different ductwork configurations from duct-fitting accessory suppliers in Canberra. 

  1. Tees 

These duct fittings are used to redirect from the main duct and join to a secondary duct. They have a letter T shape, and you can connect one end to the primary duct while the other two ends are connected to the secondary ducts.

  1. Wyes 

The Wyes can be used to join two ducts at a 45-degree angle. They resemble the letter Y and are similar to “tees” duct fittings; however, the “wyes” are linked at a 45-degree angle rather than a 90-degree one.

In order to regulate the amount of air that travels through your ducts, dampers are used to control the flow of air in the ductwork.

An internal metal plate of the duct is turned or rotated to do this.

The plenum is a box connecting your HVAC system to your ductwork and is made of sheet metal. The plenum circulates throughout the entire ductwork to distribute the air to various parts of your building once your HVAC system provides the air, whether it is warm or cool.  

They usually connect to the air handling unit at the ductwork’s end. And while they take in air, they also release it outside the house. Plenums may be acquired with the HVAC suppliers of duct fitting accessories in Canberra and come in a variety of sizes and materials. 

  1. Register boots 

The air ducts are connected to the air registers or grilles using register boots. They are made to connect to the register or grille and fit over the ducting.
