Round air ducts in Hai Phong are a type of air duct with a circular cross-section, mainly manufactured from galvanized sheet metal, stainless steel, or aluminum-zinc coated steel. They are used to transport fresh air, supply air, return air, or exhaust air in HVAC systems.
Thanks to its circular shape, the airflow inside the duct is evenly distributed, minimizing friction and pressure loss. Compared to many other types of air ducts, the round air duct in Hai Phong helps the system operate more smoothly, stably, and energy-efficiently.
Outstanding advantages of round air ducts in Hai Phong
Round air ducts in Hai Phong are a highly regarded solution in ventilation and air conditioning systems thanks to their scientific design and stable operating performance. Not only do they optimize airflow, but this type of duct is also suitable for many modern spaces, from industrial to service and commercial.
Optimize airflow and reduce pressure loss.
The round design allows for continuous airflow, without obstruction at corners like square ducts. As a result, the ventilation system achieves higher efficiency, the fans operate under less load, and energy consumption is reduced during operation.
Saves installation space.
Round air ducts in Hai Phong have a compact size, making them easy to install in technical ceilings, exposed ceilings, or confined spaces. This is an ideal choice for factories, cafes, restaurants, showrooms, and renovation projects.
High durability, minimal deformation.
With its robust construction, the round air duct effectively resists dents and vibrations during long-term operation. The use of galvanized steel or stainless steel materials ensures corrosion resistance, making it suitable for the climate and environmental conditions in Hai Phong.
Round air ducts in Hai Phong have a modern aesthetic.
Round air ducts are commonly used in industrial-style buildings with exposed technical ceilings. The duct surface can be left unpainted or painted in various colors to create an aesthetic focal point for the space.

Round ducting is widely used in many types of buildings due to its efficient air conduction, stable operation, and flexible installation. Depending on the intended use, round ducting maximizes its role in various applications, from industrial and residential to commercial and service buildings.
Applications of round ductwork in industrial areas
In factories and industrial zones, round air ducts in Hai Phong are commonly used to supply fresh air, extract hot air, remove dust, and eliminate odors during the production process. Thanks to their round cross-section, the airflow is stable, minimizing pressure loss and ensuring the ventilation system operates efficiently even during continuous operation at high capacity.
In addition, round air ducts contribute to improving the quality of the working environment, reducing temperature, and decreasing the concentration of toxic gases and fine dust in the factory space. This not only helps protect the health of workers but also increases production efficiency and the lifespan of machinery and equipment.
Round air ducts in civil engineering projects in Hai Phong.
In civil construction projects such as houses, apartments, and villas, round ducting is used for ventilation systems, supplying fresh air and extracting exhaust air in kitchens, bathrooms, and technical rooms. With its compact size and ease of installation, round ducting is suitable for limited ceiling space, especially in renovation projects or townhouses. Furthermore, its smooth operation and reduced vibration and noise help round ducting in Hai Phong meet the requirements for quietness and comfort in family living spaces.
In office buildings and shopping malls
In office buildings, shopping malls, and complexes, round ductwork plays a crucial role as an air conduit in central air conditioning (HVAC) systems. This ductwork system, combined with fans, AHUs, and FCUs, helps distribute cool or fresh air evenly and consistently to each work and shopping area.
By using compatible accessories such as elbows, round fittings, dampers, and air grilles, airflow can be flexibly adjusted to suit each functional space. This contributes to optimizing operational efficiency and saving energy for the entire building.
In restaurants, hotels, and services
For service buildings, round ducting in Hai Phong is used for kitchen exhaust, ventilation of dining areas, and air supply to central air conditioning systems. The round design helps to minimize grease buildup, making it easy to clean and maintain, and is particularly suitable for high-traffic environments.
Beyond their technical function, round air ducts are also used in exposed ceiling spaces in an industrial style. This contributes to creating a modern aesthetic for high-end restaurants and hotels.
