Product Advantages
Spiral steel wire skeleton: compressive strength is enhanced to withstand wind pressure without collapsing.
Double-layer flame-retardant PVC material: the outer layer is tear-resistant, the inner layer is smooth flow-conducting, and the UV-resistant coating extends the outdoor service life to more than 5 years.
Belted Cuff: One pull to tighten, 3 seconds to seal, no need for clamps, bolts or specialized tools. Compatible with 6-24 inches caliber equipment, fit for 90% of the mainstream fan interface.
Flexible Bending Design: 360° free steering, reducing duct layout restrictions and saving 30% installation space.
Engineering grade storage bag (Oxford Carry Bag): folded volume reduced by 70%, storage costs of only 1/5 of the traditional metal duct.
Wide temperature range performance: -15°C-80°C without deformation, suitable for cold storage, boiler room and other extreme environments.
Application Scenario
Temporary Ventilation for Construction Sites: Quickly build an exhaust system to remove welding fumes and concrete dust, and support frequent relocation.
Chemical plant gas conduction: corrosion-resistant materials to safely transport acid and alkali gases, harness interface to prevent the risk of leakage.
Smoke extraction/cooling for large events: temporary installation in concerts and sports events, rapid deployment and recovery after the event.
Agricultural greenhouse ventilation: adaptable mobile fan, seasonal adjustment of temperature and humidity, storage space saving after storage.
