Based on the advanced FCVS technology, such as a gas-liquid mixing nozzle and a multi-layer metal fiber filter, and a silver zeolite filter for the purpose of removing organic iodine. we have developed a demonstration machine for a large-capacity air purification system that purifies a large amount of contaminated air. With this acceleration and centrifugal force field of water, almost all of the fine particles in the bubbles can be transferred to the liquid phase water and dissolved. We have developed a demonstration machine of an air purification system that can remove fine particles and viruses in the air of 100 m³/h with a single nozzle and we also developed a large-capacity air purification system that can purify 2400 m³ of air per hour with 24 nozzles. The FCVS system, which is high-performance and passively activated by using SRV, is thought to help eliminate obvious infringement of personality rights, avoid litigation outages, and promote public acceptance for nuclear power to restart.
