GEP charges those sub-micron particles(0.01um) such as smoke fumes and oil-mist entering the chamber, then captures them inside the collection cell. This is done by using two High Voltage electrostatic fields inside. The HV Ionizer Field Charge the oil particles. The HV collector field push and deposit the charged oil particles on the plates. The average removal efficiency is 95%. It can achieve 99.9% by GEP ”Double-pass”configuration. GEP can eliminate all smoke discharged from Commercial Kitchen. It will be the best remedy for Kitchen Exhaustion nuisances.
