Since 1927

Mahr Maschinenbau™ GmbH,Austria was established in the year 1927 by my grandfather Mr.Matthaeus Mahr. In the same year, we installed our first bar screen at a pumping station in Vienna which operated for 75 years, which was replaced by our own rotating bar screen in 2002.

Since 1927, Mahr Maschinenbau™ has always been in the forefront of screening technology by continuously innovating products to meet  needs of operators.

Mahr Maschinenbau™  Screen technology has been involved in the US Wastewater market for several years and I am delighted to bring to you the most efficient and reliable screening technology in the world. I look forward to the opportunity of meeting your needs for your screening application and commit to providing highest quality product and service.
