Thank you for viewing. This is a SHARP high-density plasma cluster ion generator. It is from 2011. The cord clip has been replaced with a different one than the original. The desktop louver is not included. Everything in the photos is included. Estimated usage time is approximately 2500 hours. I think it can still be used for a long time. *Operation confirmed 【Product Description】 SHARP High-Density Plasma Cluster Ion Generator IG-C20-P 2-stage (High/Low) cleaning ■Ion generators wear down the needle electrodes through repeated discharge, gradually reducing the ion concentration. Therefore, even after cleaning the unit, the unit needs to be replaced after approximately 17,500 hours of total operation. ■All operations will stop after approximately 19,000 hours. ■Maximum applicable floor area: 1 tatami mat High-density plasma cluster 25000 Size: Width 86 x Height 146 x Depth 86mm Weight: 0.37 kg
