Duct flexible coupling is a very common accessory in the wind system, helping to effectively prevent system vibration and reduce noise. So what is air duct flexible coupling? What types of ductwork are available? Find out with the P69 Mechanical Factory through the sharing post below!

What is air duct flexible coupling?
Duct flexible coupling is known as a popular ductwork accessory, the product has the effect of reducing the transmission of vibrations from the fan blades in the duct.
The product designs are currently classified into many different models and categories, each with its own characteristics, suitable for many different projects such as apartments, commercial centers, basements, parking lots…
The main use of flexible coupling
In the operation of Air Duct system, when the propellers rotate, they will directly affect the inlet pipe. As a result, the efficiency of the duct is reduced, the life of the product will also be changed not to be high. As a result, the ductwork system operates smoothly, the ventilation efficiency increases, and the duct life is also increased.
Duct flexible coupling is used to connect a fan or air conditioner to the duct system, in order to reduce vibrations from the fan transmitted to the duct causing noise. The main use of flexible couplings is to isolate vibrations and eliminate installation errors.

The most popular types of flexible duct joints today
There are many coupling products on the market today. Here are the popular types
1. Round duct flexible coupling

Flexible coupling circular ductwork is a fairly common product in the ductwork system, designed in a circular or oval shape, providing high ventilation efficiency, energy-saving, and cost savings for building owners.
The product has good heat resistance, meeting the ventilation requirements in high-temperature areas. In addition, the products are also distinguished by their anti-rust, anti-wear, anti-oxidation ability, etc. Suitable for the wind tunnel system near the sea, the air is highly acidic, ensuring absolute safety in the air use process.
2. Square duct flexible coupling

The product is designed in a rectangular, square shape to help maximize ventilation, creating high performance. Square ducts are appreciated for their good heat resistance, averaging up to 320 degrees Celsius. Suitable for projects in hot areas, operating with large capacity.
In addition, the product is also highly appreciated for its ability to resist oxidation, stacking and anti-rust. Suitable for acidic environments or areas with distinctly hot and humid weather conditions, it still ensures certainty and aesthetics for the entire building.
