Plain Round Ducting

A ductwork type with a cylindrical shape and no insulation or unique features is called plain round ducting. The following are some essential features of standard circular ducting:


Shape: The cross-section of plain round ducting is circular and it is cylindrical in shape. This design is appropriate for a variety of HVAC applications since it permits effective airflow with little resistance.

Material: Sheet metal, such as stainless steel, aluminium, or galvanised steel, is frequently used to make it. A number of criteria, including cost, corrosion resistance, and durability, influence the choice of material.

Sizes: To meet differing airflow needs, plain round ducting is available in a range of sizes. Typical sizes, contingent on the particular requirements of the HVAC system, include 4 inches, 6 inches, 8 inches, 10 inches, 12 inches, and greater.

Installation: There are various ways to install plain circular ducting, such as above ground, below ground, or inside walls and ceilings. It is usually connected via slip-fit connections, crimped ends, or flanged ends to other duct components like elbows, reducers, and registers.

Applications: HVAC systems employ plain round ductwork to distribute conditioned air throughout buildings. Depending on what the system needs, it can be utilised for exhaust, return, or supply air.

Cost-Effectiveness: When considering other ductwork options like insulated ducting or ductboard, plain round ducting is typically less expensive. It provides an easy-to-use and cost-effective way to move air in HVAC systems without requiring extra features or insulation.
