The GOJEK-EAC-MAX Series is designed to treat grease, smoke, and odor emissions from exhaust ducts on
commercialcookingapplications(aswellasoilmistandsmokefromindustrialapplications).TheGOJEK-EACMAX Series can be configured with multiple stages of filtration for both particulate and odor control and is
typically furnished as a complete pollution control unit with: odor control section; exhaust fan; system rails
andnecessarycontrols.Standalonerestaurants,mixed-useandhighrisebuildings,casinos,hotels,hospitals,
corporate cafeterias, and government buildings are using GOJEK pollution control systems to alleviate the

About the Technology
CleaningtheAir
When you need one system for cleaning kitchen grease and smoke, oil mist, and contaminants, GOJEK has a

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. The ionizer consists of charged

Normally, systems are designed for collection efficiencies more than 98% or better DOP (0.3 microns).
