1. Thermal insulation and energy-saving performance

The thermal conductivity is extremely low. The thermal conductivity of mainstream materials (phenolic/polyurethane) can reach 0.018-0.036W/(m · K), which is far superior to the traditional combination of air ducts and a separate insulation layer.

It can effectively reduce the heat and cold loss of the ventilation system. According to actual measurements, it can lower the system energy consumption by 5% to 20%, and the energy-saving effect is remarkable in the long term.

The closed-cell insulation structure ensures that the insulation layer does not absorb water, avoiding a decline in insulation performance due to moisture and guaranteeing a long-lasting and stable energy-saving effect.

2. Safety protection performance

It has A fire resistance rating of A-level non-combustible standard, complies with building fire protection regulations, and does not release toxic or harmful gases in high-temperature environments, ensuring personnel safety.

It has excellent moisture-proof and mold-proof performance, a smooth surface that is not prone to bacterial growth, and no risk of fiber shedding. It is suitable for scenarios with high air quality requirements such as hospitals and food factories.

It has strong anti-corrosion and anti-aging capabilities, can withstand complex environments such as humidity and high temperature, and prevent the rusting or damage of air ducts from causing safety hazards.

3. Stable operation performance

The overall pressure resistance strength of the air duct is high. Conventional products can withstand a pressure of over 3000Pa, meeting the operational requirements of large-scale ventilation systems.

The inner wall is smooth and flat, with low air flow resistance, reducing airflow noise. At the same time, it lowers the operating load of the fan and enhances the operational efficiency of the system.

The integrated molding structure has no seams at the joints. Its air tightness far exceeds that of traditional air ducts, and the air leakage rate can be controlled within 1%, avoiding energy waste.

1. Construction convenience

The product is lightweight and high-strength, with the weight of a single section being only 1/3 to 1/4 of that of traditional iron sheet air ducts. It does not require large hoisting equipment and can be transported and installed by a single person.

It adopts a standardized module design with complete accessories. On-site, only simple splicing and fixation are required, without complex processing procedures, reducing the construction difficulty.

It is compatible with multiple connection methods and can flexibly handle complex pipeline layouts such as right-angle and three-way pipes, meeting the installation requirements of different buildings.

 

2. Efficiency and Cost

The installation efficiency is extremely high. Compared with the traditional construction of air ducts and insulation layers, the construction period can be shortened by 30% to 50%, significantly reducing labor costs and construction period costs.

Factory prefabricated production ensures high dimensional accuracy. No on-site cutting or adjustment is required, and the material loss rate can be controlled within 2%, reducing material waste.

No subsequent secondary treatment procedures such as insulation and anti-corrosion are required, reducing construction steps, lowering the risk of cross-operation, and enhancing construction safety.

1. Service life

The combination of high-quality base materials and composite processes results in excellent compressive strength, wear resistance and anti-aging performance. Under normal usage conditions, its service life can reach over 20 years, far exceeding the 10 to 15 years of traditional air ducts.

 

2. Comprehensive cost

Although the initial investment is higher than that of traditional air ducts, combined with advantages such as energy conservation and consumption reduction, shortened construction period and reduced maintenance, the payback period of investment can usually be controlled within 2 to 3 years.

The long-term operating cost is low, and it can save a large amount of energy consumption and maintenance costs every year. The full life cycle cost is 20%-30% lower than that of traditional air ducts.

 

3. Maintain convenience

The surface is smooth and easy to clean. It only requires a simple wipe in daily life to remain clean, without the need for complex maintenance procedures.

Applicable scenarios

Commercial buildings: shopping malls, office buildings, hotels, etc., meet the demands of large-scale ventilation and energy conservation, and enhance indoor comfort.

Public facilities: hospitals, schools, airports, high-speed railway stations, etc., are suitable for high safety, high hygiene standards and complex installation environments.

Industrial sites: electronic factories, food processing plants, clean workshops, etc., to meet the requirements of high-precision ventilation and cleanliness.

 

Competitive advantage

Compared with traditional air ducts, it has core advantages such as integration, energy conservation and efficient installation, and solves the pain points of traditional air ducts such as insulation layer detachment, high air leakage rate and complicated construction.

Compared with ordinary prefabricated air ducts, it has superior insulation performance, fire resistance rating, durability and other aspects, and is suitable for the demands of high-end buildings and harsh scenarios.
