The Pfannenberg PTF 61.000 11681102055 is a high-performance Filterfan 4.0 roof-mounted filter fan designed for efficient thermal management of electrical enclosures, control cabinets and industrial automation systems. Operating from a 230 V AC supply, this IP54 version combines powerful forced-air ventilation with filtered enclosure protection for demanding industrial applications.
The roof-mounted design extracts rising warm air from the enclosure, supporting natural convection and helping provide an even temperature distribution around sensitive electrical and electronic equipment. Pfannenberg's patented quick-fastening system enables tool-less mounting, while the filtered IP54 configuration helps protect cabinet components against dust and water ingress.
With an unimpeded airflow of 880 m³/h and an airflow of approximately 570 m³/h when used in a matched filter fan and exhaust arrangement, the PTF 61.000 delivers substantial cooling performance for cabinets with significant thermal loads. Its approximately 470 × 470 × 152 mm external dimensions and standard 291 × 291 mm mounting cut-out simplify integration into industrial enclosure systems.
Roof filter fans such as the Pfannenberg PTF 61.000 provide an effective method of removing heat from electrical cabinets by extracting warm air from the upper section of the enclosure. Because heated air naturally rises, roof mounting supports natural convection while forced airflow helps maintain more consistent internal temperatures and reduce potentially damaging thermal hotspots.
The IP54 version of the PTF 61.000 combines high airflow with G4 filtration, making it suitable where filtered ventilation and improved ingress protection are required. Its standardised cut-out and tool-less fastening system also help reduce installation and maintenance time in machinery, automation and control-panel applications.
