Connection Ways of Ventilation Ducting


In coal mining, tunnel and other underground project. Connection way of ventilation ducting has great effect on ventilation efficiency, especially in long distance ventilation. There must be low wind age, low air leakage and easy to install etc. It should ensure local ventilation safety and reliability. Now there are four connection ways in the domestic and overseas. Connecting with End Ring and Industrial Zipper.


  1. Connecting with end ring is that coiling the ventilation duct on end ring, and putting one end ring into another and then drawing two ventilation ducts to make them being tight. This connection ways save installing time and effort with no need for wire. Easy to install and take down.
  1. Connecting with zipper coupling is that using zipper to connect each ventilation hose. It is easy to install and connecting is tight.

Connector of ventilation hose is main cause which increase wind-resistance and have air leakage. Making ventilation hose increase to 30m,50m or 100m and reduce connectors. They are efficient way to reduce wind-resistance. Moreover, we should ensure the quality of connectors, the installation quality and maintain regularly. Only do these can we make our ventilation system better.


Sulong Eco-Technologies can provide both the design and construction of virtually anything that can be made from PVC coated polyester fabric. This fabric is air and waterproof, chemical and fire resistance, and UV protected from sunlight degradation.


Our rich experience in PVC coated fabric enable us to find innovative new products for the industry.
