Advantages of Circular Air Ducts

It is the much more commonly used channel type. Round ducts have many advantages, such as increased airflow, quick installation and lower costs. If you are trying to create a quiet, attractive workspace for your employees and customers, then the circular duct is definitely the choice.

• Less Friction.
• More Efficient Airflow.
• Better for Medium to High
• Pressure Systems.
• Installation Easier and Less Cost.
• Less Noise Pollution.

Disadvantages of Circular Channels

Circular air duct is not suitable in some cases. The reason is Circular ducts take up more height than rectangular or square ducts. It therefore means that Circular ventilation ducts will not fit in tight spaces. So it means it’s technically less efficient in terms of maximizing airflow.

• Takes More Space (Higher).
• Not Efficient for Low Pressure Systems.
• Difficult to Connect Fancoil to Main Channel.

► Square Channel System

Advantages of Square Air Ducts

In which situations should the Square Channel system be used? As mentioned earlier, square ducts are necessary when you have a narrow space that will not allow the height of circular ducts. These rectangular or square air ducts also solve the unsightly connection problem between the fan coil and the main duct.

• It occupies less height, so it saves space in spaces.
• Easily connects the fan coil to the main duct.
• Better for low pressure systems.
• It may be more suitable for use in spaces and structures such as warehouses, lofts and bars.

Disadvantages of Square Channel System

*They allow more noise out of the duct, which can cause many problems if you are trying to create a safe and quiet working environment.

*Rectangular-Square HVAC Air Ducts Are More Costly To Install Initially.
