The 1950s were a critical time period for industrial development in Germany. Creative and hard-working people laid the foundation for economic reconstruction. One of them: Otto Pfannenberg.

In 1958, four years after founding his own company, this Hamburg based electrical engineer achieved a revolutionary invention. The Filterfan^® allowed a higher degree of safety in the management of modern manufacturing processes.

Otto Pfannenberg's main focus was the development and assembly of electrical enclosures, which became more and more widespread throughout production facilities. He regularly encountered the problem of overheating components in control cabinets.

With the development of the first Filterfan^®, he presented a ground-breaking solution to counter these heat related issues and the rest is history. Our company's success begins here. From generation to generation, our world-class engineers have been working on the continuous technological development of Pfannenberg Filterfan^® products. Numerous improvements are continuously made including several breakthroughs, so valuable that they required international patents. All in all our Filterfans 4.0™ contain 11 field-proven patented features.

It is an honour for me to celebrate the 60th anniversary of our Filterfans^®, together with our partners and everyone who has been involved throughout the years.

It is safe to say, that Pfannenberg's Filterfans^® set a high benchmark in today's industrial market; resulting in a market position that we want to retain in the future – with the passion that has driven Otto Pfannenberg: the passion for new ideas.
