Smoke Removal System

I have long dreamed of having a good smoke removal system, but I always encountered a problem - I couldn't find a suitable flexible hose. But one day, I saw a manicure fume extractor, and there was a separate tube available for it. Without missing this opportunity, I purchased it. Developing the actual system didn't take much time, but selecting the right fan turned out to be a challenging task. I tried domestic axial fans, turbines, and similar ones used in air conditioners, but only in a smaller format. Finally, I was able to try a server turbine of the 9733 format, and I settled on it. However, there were some surprises waiting for me here... The very powerful fans turned out to be too noisy, while the quiet ones were too weak. But I found the perfect balance and chose a turbine with 4000 revolutions per minute and a 12-volt power supply. I also tried a turbine with 8000 revolutions, and although it works incredibly well, the noise becomes an issue for extended operation. Ne
