Filter fans FL-Series
Heating, cooling, climate, electrical power control. Since more than sixty years. DBK s knowledge of thermal management gives us the experience to guide and support you with your technical challenges - we can manage the complete project from concept to full production release. Filter Fan Filter Fan units for installation in electrical cabinets and enclosures in which excessive heat develops due to high density of equipment. Overheating threatens to cause damages to the equipment inside. Filter Fan units with separate exit filter force cool air from the outside into the cabinet and remove warm air from the inside. By reducing the temperature inside the cabinet the highly sensitive electronic components are protected from overheating. The FL series by DBK offers Filter Fan units of different sizes for various cooling needs. F 25 F 24 F 15 F 17

A slight overpressure inside the cabinet will make sure that the air is directed through the filter and fan into the cabinet, thus the air is filtered and clean.
