Overview
Our flat PVC mining ventilation duct with zipper connectors is specially designed for mines and tunneling projects. It's a revolutionary ventilation solution that combines efficiency, durability, and convenience.
As the name suggests, the core feature of this duct is its unique "zipper coupling" design. Like a custom-made "jacket" for the ventilation system, it allows for quick, airtight connections between duct sections and between duct and fan with a simple zipper-type operation.
