The GOJEK-EAC-MAX Series readily adapts to the various air collection methods utilized to recover contaminantsforcollection. PrincipalsofOperation The GOJEK electronic air cleaner is technically known as an Electrostatic Precipitator (ESP). In this type of equipment, all airborne particles,even of microscopic size, are electrically charged (positively) as they pass throughahighvoltageionizer.Thesechargedparticlesarethenattractedtoandadheretoaseriesofparallel collecting plates, which form the negative elements of an electrostatic field.

Normally, systems are designed for collection efficiencies more than 98% or better DOP (0.3 microns). Collecting a contaminant at these efficiencies, especially when there are high concentrations, can result in largeaccumulationsinarelativelyshortperiod.maintenanceoftheGOJEK-EAC-MAXSeriesshouldencompass twoareas:theoperationoftheequipmentforefficientcollectionandthesystematicremovalofthecollected contaminant. 3 www.gojekesp.com How It Works Gojekhighefficiencyelectrostatictechnologyprinciple-photoionization Coronastartingstage Flowphotoionizationstage Under certain DC voltage,nagetive corona or positive corona gathers space After the first corona stage is completed,follow the DC voltage increasing,the chargeandhighenergyelectronsneartheelectricvalue.Inordertominimize high-energy electrons and space charge will be converted into free electrons the amount of ozone generated,positive electricity Ionization technology is andfreecharges.Atthisstage,thepositivechargeisdrivenawayfromthespace adoptedforfumepurifier. oftheelectrodetoformpositiveions,andozoneisalsomainlyatthismoment.
