Kylin has over 15 years of experience in fabric air duct systems for HVAC applications. Our ducts are made from IFR polyester oxford fabric, meeting international fire safety standards such as NFPA 701 and DIN 4102-B1. We offer various fabric weights for customization based on customer needs.
Our fabric ducts provide efficient air distribution, eliminate condensation, and maintain hygiene. They are washable, reusable, and designed for long-term performance—lasting over 15 years. Lightweight and easy to install, they are ideal for large spaces like industrial plants, sports halls, and supermarkets.
We cater to specialized environments like clean rooms, laboratories, and data centers, where strict air quality control is required. Our ducts are also used in commercial spaces such as offices and retail stores, improving air circulation while enhancing aesthetics.
As a fully integrated manufacturer, we manage the entire production process, ensuring tailored solutions that optimize comfort, energy efficiency, and cost savings. Our fabric ducts reduce installation and operational costs by up to 70% compared to metal systems.
With a delivery time of 10-15 days and a low minimum order quantity of 200 square meters, Kylin serves major clients like JD Logistics, Sun Flower, Dali Food Vanguard, RT-MART, and GREE. We continue to lead in advanced air distribution, providing high-quality, cost-effective systems worldwide.

2026-09-21Material choice starts with the fire specification, because it is the one requirement that cannot change late in a project. For most HVAC projects we recommend inherently flame retardant (IFR) polyester, where the flame retardant is built into the fiber and stays effective through regular cleaning. Our flame retardant polyester Oxford fabric in 300D and 600D for HVAC ducts is made to meet NFPA 701 and DIN 4102-B1. Where a specification calls for a non-combustible material, as some data center and high-risk building projects do, our non-combustible fabric duct for projects with strict fire specifications is the option to discuss.
Fabric weight follows duct size and system pressure. 300D suits small to medium diameters and clean indoor spaces, while 600D suits larger diameters, higher pressure and ducts that are removed for washing. A fabric duct needs a design static pressure of roughly 150 to 200 Pa to inflate properly, so let the fan curve guide the weave.
Permeability is the last decision. Micro-porous fabric releases a small share of air through the weave for a gentle, draft-free supply in occupied spaces and food areas, while non-permeable fabric with laser-cut orifices or nozzles gives longer throw and more precise direction. In hygiene-sensitive rooms, antimicrobial, anti-static and low-shedding finishes are common.
A fire report applies to the fabric that was tested, so match the report to the weight, weave and color you order. NFPA 701 tests flame propagation in textiles and is widely quoted, DIN 4102-B1 is the German class for materials that are difficult to ignite, and EN 13501-1 is the European Euroclass system.
Start from the room: ceiling height, how far the air must travel, and how much clearance the ceiling offers. Small-hole outlets suit standard indoor spaces, micro-porous outlets give low-velocity air for occupied and clean areas, slot outlets spread air evenly along the run, and nozzles concentrate the air into fast jets, with outlet velocity around 15 m/s, for high ceilings and long throw. If people stand directly under a low duct, begin with micro-porous. If the duct hangs high above a large open floor, begin with nozzles and check that the throw reaches the occupied zone.
Round is our default shape because it inflates most evenly and gives the most capacity for the fabric used, as in our circular fabric duct for open ceilings. Where headroom is tight, the semi-circular fabric duct for low ceilings and flush mounting sits close to the ceiling or wall, and the quarter-round fabric duct for wall and ceiling corners fits the junction. Oval and fan-shaped profiles are made to order.
Suspension is planned at the same time. Cable suspension at about 7 meter intervals suits long straight runs, rail systems suit ducts that come down for cleaning, and our bracket type fabric duct for rigid mounting suits fixed installations. Settle the outlet type and shape first, then confirm the diameter from airflow and the fan's design pressure. The full range is on our fabric air duct range for HVAC air distribution.
The right setup changes with the building, because each one has a different priority. Here is how we approach the most common ones.
In food processing plants, we recommend micro-porous or small-hole outlets with IFR polyester and an antimicrobial finish, machine washable below 40 degrees Celsius. Where flour, oil or fat is in the air, shorten the cleaning interval. In supermarkets, retail stores and offices, low-velocity micro-porous or small-hole supply keeps air draft-free, and the fabric can be color matched to the ceiling or brand palette.
Sports halls and warehouses depend on throw distance, so nozzle outlets aimed at the floor work best, with 600D fabric for larger diameters and cable or rail suspension. In cleanrooms and laboratories, micro-porous or slot outlets with low-shedding material such as our purified type fabric duct for clean and controlled environments suit the strict air quality target. In data centers, slot or micro-porous outlets give even cold aisle distribution, and the fire specification usually decides the material, so it helps to confirm it with the fire engineer early.
Fire requirements differ from market to market, so we ask every export customer for the target standard at the design stage. North American projects follow mechanical and fire codes together with local authority rules, so the project engineer's requirement is the one to work from. In Europe, EN 13501-1 is the governing classification, and DIN 4102-B1, one of the standards our duct fabrics are made to meet, is still common in German-speaking markets. Chinese projects normally quote a class under GB 8624, and markets such as Japan, Korea, the Middle East and Latin America follow national fire service rules and local approvals.
Send us your target market and required standard before quotation. We will check the requirement against our available fabrics and tell you plainly what fits, through our contact page for fabric duct quotations and compliance questions.
