A particulate filtration system 10 for removing particulates suspended in a fluid that includes: a filter element 120, a pre-collector body component 130 operably connected to the filter element and capable of receiving an electrical charge to attract and remove particles suspended in the fluid and means for cooling the pre-collector body component. The means for cooling the pre-collector body component 130 may include a convective cooling channel through which a coolant flows. The system 10 may further include a discharge electrode 160 spaced apart from the pre-collector body component. The discharge electrode 160 may be capable of receiving an electrical charge causing a difference in the electronic potential between the pre-collector body component and the discharge electrode. Advantageously larger particles are more likely to attach to the pre-collector leaving smaller charged particles to gather on the surface of the filter element creating a porous dust layer which reduces or eliminates pressure drop problems.
