Overview

Our duct is specifically designed for high negative pressure, high abrasion, and complex, harsh environments, aiming to solve industry pain points such as the susceptibility to damage, aging, poor wear resistance, and low pressure resistance of traditional ventilation ducts.

It utilizes advanced composite materials and a reinforced structure, integrating high-strength skeleton materials with a specially formulated wear-resistant synthetic PVC coated fabric. It can withstand powerful negative pressure suction without deformation or collapse, while resisting the continuous erosion of the duct walls by rock fragments, ore, and particulate matter, resulting in a service life far exceeding that of ordinary ductwork. Whether used for gas drainage in coal mine roadways, dust removal in tunnel excavation, or ventilation in large warehouses, this negative pressure ventilation duct provides a stable and reliable solution.

Applications

Industrial plants: The ventilation ducting can bend freely to accommodate to a variety of complex plant structures.

High-rise buildings: Our flexible spiral ventilation ducting can pass between high floors to meet large area ventilation needs.

Mines and underground tunnels: Providing fresh air for mines which can effectively reduce the concentration of explosive substances such as gas and coal dust in underground coal mines and reduce the occurrence of safety accidents.
