It's amazing. I'm not good at English, so I don't understand the story of the video, so I'm asking you a question. This "hydrovent" not only expels smoke to the outside, but also extinguish it, right? Is that the principle of lowering the oxygen concentration inside? If you use a hydrovent on the other side to take the air out Eventually, air is sucked into the other passage and oxygen is supplied, so I think the fire will grow, which is amazing. Thank you for the video. Thank you.
Sorry for late to answer your question. Basically, this equipment designed based on 'Bernoulli's equation'. This tool can use for fire extinguish, but the main purpose is suck the smoke from the building. so, early fire suppression is most important before use this tool. This tool can't extinguishing fire alone. Anyway, not just suck the smoke from the building, also suck the air and make building vacuumized. then remain fire in the building is extingished cause lacks of air. I hope this will help for your understand. Thank you.
