We know that electrostatic precipitator air filters are mainly used in artificial leather foaming/coating lines to collect DOP oil in the exhaust at the same time filter the exhaust. The smoke from foaming production lines contains lots of grease& oil and in a high temperature. That is easy to catch fire inside machines. The PVC leather factories used to use the big tower ones which don’t have any fire suppression system or equipment inside the machines. That is nothing can do if any sparking inside.
Boton Air industrial electrostatic air cleaners have heat exchangers to cool down the exhaust first which help for a better efficiency at the same reduce risk of catching fire. Also fire dampers are on both sides of ESP filters to protect the machines from damaging from fire.
