[Experimental Video] Smoke Elimination Experiment Using High Voltage (Smoke Elimination Device)!

[Experimental Video] Smoke Elimination Experiment Using High Voltage (Smoke Elimination Device)!

YouTube channel launched! We will clearly introduce smoke elimination experiments using high voltage from a small high-pressure power supply in videos.

We will introduce a smoke suppression experiment utilizing high voltage from a small high-voltage power supply in a video. When the high-voltage power supply is OFF, smoke passes through the container and comes out from the fan. When the high-voltage power supply is turned ON and high voltage is applied to the electrodes inside the container, corona discharge begins from the electrodes, and the charged smoke (components) adheres to the walls of the container, preventing the smoke from coming out. Green Tech will continue to conduct various experiments and proposals utilizing static electricity, discharge, and charging. If you are interested, please take a look! *Please watch the experimental video in the middle of the page. 　　　　　　　　　★Free Demo Available★ If you visit Green Tech, we will provide a free demonstration of the actual equipment. If you would like to "see the lineup" or "test/verify with the actual equipment," please contact us using the information below. *We also accept contract manufacturing of high-voltage power supplies. Please inquire first.
