| Sleeves or Ventilation Ducts | | | Deltavent: A product especially designed to be used in forced ventilation (positive pressure) in the process of injecting fresh air into tunnels or galleries. | | | It reacts to volumes of flow and high volumes necessary for different mining or tunneling activities. Because they’re built light, resistant, and flexible, Deltavents reach different places and tasks easily and efficiently through accessories such as Yes, Tees, elbows, reductions, etc.
| | |  | Suction Deltaducts | | | | It’s a duct especially manufactured to evacuate air, gas, and dust in the different mining tasks or in the construction of tunnels, galleries, etc.
| | | | It has a structural reinforcement that is made of metal or synthetic rings that are located successively along the sleeve, making a stable, resistant, and light system. | | | | It’s designed to resist the negative pressure (suction) caused by the extractors in the process of evacuating air from the tunnel or the gallery.
| | | | It can also be used to blow air (positive pressure), which adds versatility to the duct. | | | | In both cases, there are a number of different types of couplings that can be used to have the perfect joining and to extend the route, which are: Yes, Tees, reductions, derivations, etc
| | | | Warranty | | | | Deltaducts are manufactured with the highest quality canvas, according to the high demanding tasks in a mine which are: impermeability, resistance to the impact of fragments that occur during blowups, no open flame spreading (anti-flame material), and other characteristics that make it reliable and safe.
