Since 1995, Biyang from China has engineered, manufactured, and distributed industry leading underground ventilation products to the mining and tunneling companies.  Our proud history has guided us to fully understand the requirements and adapt them into our practices to be able to produce the best quality demanded by the industry’s largest retailers.

The underground ventilation duct serves as the air pathway through steel-coiled ducts, allowing the fresh air to circulate while removing dust and noxious gases.  Commonly referred to as mining ducts, these are used for ventilation system in underground workings, such as mine and tunnel construction, or in any environment where pressure is required.

The industrial flexible ducts are ideal for mining, tunneling, and lab or factory workings.  Biyang produces their very own PVC laminated industrial flexible ducts with better ventilation performance.  For PVC coated lay flat ventilation ducts, we utilize high strength welding technology to achieve low-friction, flexibility and lightweight design.  These two types of mining ducts are easy to transport, easy to assemble, performs beyond expectations.
