The filters with fan channel the cooler, filtered external air inside the electrical panel removing any dirt, dust and particles that could damage the components of the electrical panel. The filter fans also expel the hot air through ventilation grids or roof exhaust units.

　　Roof exhaust units are used in electrical panels located in confined spaces and provide direct heat extraction through the upper area of the electrical panel. These units can be coupled to a filter to obtain natural or forced convection air cooling (fan version only).

　　The airflow generated by the filter fans and roof exhaust units make it possible to maintain a more even temperature inside the electrical panel, protecting the electronic components from overheating.
