DFT Filter Systems: Our Success Story

1947 Founding Year
Hermann Deichmann opens an engineering office at Bebra in Hesse. Three years later the young company becomes involved for the first time in maintenance work for ventilation systems.

1953 Deichmann Bag Filter
The company is awarded the patent for the development of the revolutionary Deichmann bag filter. Four further future-oriented developments are also patented.
The manufacture of complete filter systems starts a little later.

1980 Deichmann Bag Jet Filters
In the early 1980s the time is ripe: Development and production of the Deichmann self-cleaning bag jet filter commences. An innovation, which enables customers to use the filters continuously without the need for stoppages for cleaning.

1991 Self-Supporting Filter Media
In the early 1990’s, the development and patenting of novel, self-supporting filter media begins which substantially reduce the amount of material required for complete filter systems. Spiral tubular filters are developed ready for series production – thereby adding high-performance compact filters to the product range.

2000 Deichmann as a System Provider
Around the turn-of-the-century, the Deichmann Umwelttechnik GmbH advances from filter supplier to system provider. The “one-stop shop” philosophy provides the customer with more options and strengthens the company`s market position considerably.

2008 Integration within the GEA Group
In October of that year, the Deichmann Umwelttechnik GmbH is integrated into the GEA Group – a technology concern. As part of this globally active organisation, Deichmann continues to grow its international activities as a supplier of complete system solutions.

2015 Operation “Clean Air”
GEA Group becomes increasingly involved in the components business and Deichmann is spun off and fused with the globally active CFH Group. By the addition of Deichmann Filtertechnik, the Holding Company, which is focussed on workplace safety and clean air isues, rounds off its product portfolio with high quality, individual dedusting solutions for surface and underground applications.
