Insulated fabric ducts, as a new type of flexible ventilation system, are gradually replacing traditional metal ducts in industrial plants.   Their biggest advantage is high-efficiency insulation: made with composite insulation fabric, they reduce energy loss by more than 30%, making them suitable for scenarios requiring constant temperature control and reducing operational energy consumption.   Secondly, their uniform airflow is well-suited for large industrial spaces: combining infiltration and jet-type air delivery, they can cover factory buildings with heights exceeding 8 meters, avoiding the impact of excessive localized temperature differences on production precision that can occur with traditional ductwork.   Furthermore, they weigh only 1/10 of metal ducts, reducing the building's load-bearing capacity and shortening the installation period by 50%; their detachable and washable structure meets the hygiene requirements of dusty environments, reducing maintenance costs by 40%.   This system is widely used in various industrial plants and logistics centers, improving environmental comfort and helping enterprises save energy and reduce costs, making it an ideal choice for industrial ventilation.

Steel cable suspension systems are simple to install and relatively inexpensive. They are categorized by the number of suspension rows: single-row, double-row, and multi-row.   Single-row steel cable suspension systems are generally used in locations with small pipe diameters or poor ventilation where aesthetics are not a primary concern. Single-row systems are very simple and practical, typically oriented at the 12 o'clock position.   Double-row steel cable suspension systems are generally suitable for locations with larger pipe diameters. In the absence of ventilation, duct sagging can affect the area below the pipe. Double-row steel cable suspension systems are the most common installation method, with common installation orientations being 2 o'clock, 10 o'clock, 3 o'clock, and 9 o'clock.   Multi-row steel cable suspension systems are generally suitable for locations with larger duct diameters where aesthetics are a priority.

Our company has successfully finished the manufacturing and on-site installation work for a battery workshop project located in Sichuan Province.

In tall and complex industrial plants, fabric ducts are becoming the ideal choice for ventilation systems.   Using lightweight, flame-retardant fabric, they are easy to install and significantly reduce the structural load on buildings. Through fiber permeation and orifice jet technology, they achieve uniform airflow, precisely meeting the air supply needs of workstations or special work areas.   Compared to traditional ducts, fabric ducts have lower air resistance, reducing fan energy consumption by more than 15%. Combined with their uniform airflow design, the overall air conditioning load decreases by 20%.   Their anti-condensation and easy-to-clean properties reduce maintenance costs to only one-third that of metal ducts, while effectively inhibiting mold growth, meeting the cleanliness requirements of industries such as food and electronics.   From machining to warehousing and logistics, fabric ducts, with their high efficiency, energy saving, comfort, and cleanliness, safeguard the industrial production environment.

We’re going to look at how fabric air ducts stack up against metal sheet ducts when it comes to noise control. Standard metal sheet ducts push air out fast through limited outlet openings, which often creates loud wind noise plus mechanical shaking.   Fabric ducts work differently: air seeps out slowly through tiny holes spread all over the duct surface, cutting down wind noise right where it starts. The fabric material soaks up noise from inside the ventilation system, and unlike rigid metal, soft fabric won’t vibrate or produce resonant hums. The end result is even air distribution with much quieter operation, making indoor spaces far more pleasant acoustically.

The fabric of the duct for fiber materials has extremely strong tensile strength and tear resistance, enabling the material to fully exhibit its optimal properties. The product has passed the national fire safety inspection and remains at its original fire rating even after being cleaned 50 times. For purification workshops, it can ensure that the air supply is dust-free, and by means of laminar flow, it can push the dust particles to the ground, ensuring overall cleanliness. At the same time, it has excellent antibacterial properties, fully meeting the strict requirements for safety, cleanliness, and hygiene in industries such as healthcare, electronics, and food.

1. Will the fiber fabric ducts get moldy or cause condensation?  The fabric has a special antibacterial treatment function. During the ventilation process, the duct remains dry at all times, so it won't get moldy. Due to the duct material's micro-permeability, in the cooling condition, the temperature difference between the inner and outer walls can be eliminated through the permeation effect on the pipe wall, thus avoiding the formation of condensate water.  2. The service life of fiber fabric ducts?  All the ducts are made of fiber filaments and have undergone special treatment. They can usually maintain their original properties after being cleaned more than 50 times. The service life of the fabric is generally over 15 years.  3. What is the pressure loss of the fiber fabric duct?  Generally speaking, the ducts should be kept fully inflated and a certain static pressure must be maintained inside the ducts. The magnitude of this static pressure is usually related to the weight of the ducts, and the pressure loss of a straight duct is typically 1.5 Pa per meter.  4. What is the cost of the fiber fabric ducts?  The overall cost of fiber fabric ducts is usually 10% to 30% lower than that of traditional iron sheet ducts. Moreover, the larger the project scale, the more significant the cost advantage becomes.  5. Is the installation of fiber fabric ducts convenient?  Usually, the installation is organized by the customers themselves. Due to its simple installation process and light weight of the product, the installation period is only one fourtieth of that of traditional iron sheet ducts. Generally, two construction workers can complete the installation of no less than five ducts in a single day.  6. Can Bruno provide the design?  Our company has a professional design department and dedicated design staff. Customers only need to provide the project floor plan, the location of the main unit and relevant parameters, and our company can complete the design of the optimal ventilation scheme for free within three days.

The pharmaceutical industry has strict compliance requirements for the temperature and humidity stability and hygiene cleanliness of drug storage. Compared with traditional metal ducts, fabric ducts have significant advantages in adapting to the scenarios of pharmaceutical warehouses. The key points are as follows:  1. The air supply is uniform. Through the surface's porous/micro-porous structure, it achieves full-area, no-corner air supply, which can control the temperature and humidity difference within the warehouse to an extremely small range. This is suitable for the storage needs of sensitive drugs such as vaccines and biological preparations, and can eliminate the risk of drug failure caused by local temperature and humidity exceeding the standard.  2. Naturally anti-condensation. The fabric has inherent micro-permeability properties, and there is no significant temperature difference between the inside and outside of the tube. This fundamentally prevents condensation problems, preventing condensate droplets from contaminating the drugs or breeding mold, and meeting the strict requirements for dryness and cleanliness in the pharmaceutical warehouse.  3. Low-noise operation. The flexible fabric has no hard pipe wall friction resonance, and the operating noise is much lower than that of traditional ducts. It can create a quiet working environment for staff, reducing the error rate of meticulous tasks such as inventory and verification.  4. Easy to maintain. It mostly adopts quick-disassembly design, allowing for easy disassembly for cleaning and disinfection without the need for complex tools. This results in lower maintenance costs and better compliance with GMP and other hygiene standards audits, preventing air quality risks caused by the accumulation of dust and bacteria.

In the construction process, the fiber fabric ducts are produced in the factory in a standardized manner, eliminating the need for secondary processing on-site. This results in a fast installation speed and low labor costs. In contrast, metal ducts require on-site cutting, welding, and fabrication of flanges, which involves complex procedures, a long construction period, and a large number of workers.  In terms of operating energy consumption, fabric ducts can provide uniform air distribution, avoiding local undercooling or overheating, and the energy consumption of the fan is lower; metal ducts rely on terminal devices such as diffusers and air outlets to supply air, with concentrated airflow, which is prone to local undercooling or overheating, and thus has higher energy consumption.  In terms of maintenance and management, fabric ducts can be disassembled in modules and washed directly by machine, making them particularly suitable for high-cleanliness environments such as those in food and pharmaceutical industries. On the other hand, the interior of metal ducts is difficult to clean, prone to accumulating dust and breeding bacteria, and the maintenance cost is high.  

Supermarkets and shopping malls, due to the large population density and noisy environment, the ventilation environment can directly affect the quality of the supply products and the mood of customers when shopping, so a good air supply system is particularly important. In view of the characteristics of such commercial places such as large area, high level, large flow of people and close space, the traditional diffuser air supply position is fixed, low flexibility, and can not achieve sufficient ventilation volume. The fiber fabric air duct system is made of small breathable fiber material, combined with professionally designed laser jet holes, which can quickly send most of the air volume to the required area, effectively reduce the heat and cold energy loss in the air volume transmission process, and the air supply volume is large and uniform, both cold and hot air supply effect is very good, meeting the ventilation requirements of large occasions. The fabric duct system has a variety of colors, shapes can be selected, all kinds of decoration styles, simple, beautiful and high-grade appearance, providing internal support type fabric duct solves the traditional fiber fabric duct does not blow the state of dented shape. The material weight of fiber fabric air duct is lighter than that of traditional iron sheet air duct, only 240g per square meter, industrial production of finished products, on-site installation is simple and convenient, greatly saving installation time, and can make a great contribution to the profit of commercial places as soon as possible. Bag air duct system, based on years of experience in commercial super industry application, combined with feedback from the owner. A complete supermarket application scheme was designed to solve a series of problems, such as the traditional fiber fabric air pipe on the preservation of vegetables in the supermarket and the influence of ultra-low height of underground store on customer comfort. At the same time, according to the national health norms, the air conditioning and ventilation system must be cleaned regularly, the fiber fabric air duct system has an absolute advantage in this regard, and the cleaning does not affect the normal business at the same time, and the cost is only 1/15 of the traditional. Compared with the difficult problem of cleaning and maintenance of traditional iron sheet air duct system, air duct is more suitable for the use of commercial supermarkets.    

Today, we will compare the advantages of fabric ducts and iron sheet ducts in terms of noise reduction. Traditional iron sheet ducts rely on high-speed air flow being ejected from local air outlets, which easily generates significant wind noise and vibration.   In contrast, fabric ducts deliver air at a very low speed through evenly distributed micro-holes on their surface, reducing air flow noise from the source. The fabric material itself has sound absorption properties, which can absorb internal noise in the system.   Meanwhile, the soft fabric avoids the vibration resonance that is prone to occur in metal ducts. This enables fabric ducts to achieve uniform air distribution while effectively lowering the overall noise level and enhancing the acoustic comfort of the indoor environment.
