Filter Fans

Filter Fan units designed for retro-fit installation in electrical cabinets and enclosures where excessive heat develops, due to the high density of equipment, and overheating threatens to damage the components inside.
Filter Fan units, with separate outlet, filter force cooled air from the outside into the cabinet and remove warm air from the inside. By reducing the temperature inside the cabinet sensitive electronic components are protected from overheating.
The FF series is available in different sizes for various cooling needs.
