The company ABN Apparatebau Nittenau GmbH was founded in 1982. ABN has taken over the production of compressors and vacuum pumps from the company AOA Gauting which had until then a branch factory on the company site. The company is still today acting in the field of fuel pumps for aerospace technology. This know-how is also a part of the development of oil-free membrane technologies for compressors and vacuum pumps. In 1988 at ABN began under the guidance of the today`s manager Mr. Karl Heigl the active marketing of eco-friendly and long-lasting membrane technologies. Today ABN is proud to say that this technology is advancing worldwide - because of its oil-free components it makes an important contribution to the environmental protection. It was and it is still today very important for the constant success that all members of staff are working with the following business philosophy: Quality is when the customer comes back – and not the product.
