An Electrical Panel Fan Filter is a device designed to cool and protect electrical enclosures or control panels by regulating airflow and preventing the accumulation of dust, debris, and other contaminants. The fan filter works in tandem with a ventilation system, where air is drawn through the filter to allow for the removal of heat and particles that can damage internal electrical components. These filters come in various types and are used in different settings, depending on the level of protection and cooling required.
