Pfannenberg filter fans work using the principle of natural convection they cool the components with the the cabinet to which they are fitted. The filter in the fan stops a build up of dust gathering on the components. This is important as this dust can have insulation properties that can cause the components to over heat.
The filter fan assembly includes a fan and twin finger guards to enable filter replacement without switching off the supply
