Over 50 years of success - reduced to the essentials

bg filtration gmbh is a manufacturer of high-quality filters and separator systems for a wide range of industrial applications worldwide. With the traditional brands AEROB and bg textile air engineering, decades of experience in dedusting, filtration and air conditioning technology are combined under one roof.

The company's history begins in 1971 with the founding of AEROB Entstaubungstechnik in Wehingen. In 1980, the company moved to the production building in Renningen. In 2009, the traditional brands AEROB Entstaubungstechnik and LTG Textillufttechnik were merged to form LTG AEROB Filtration Solutions GmbH.

2013 marked a turning point with the reestablishment of bg filtration gmbh and the continuation of the AEROB and LTG Textile Air Engineering brands. In the years that followed, the company expanded continuously with sales partners in Switzerland, Italy, Romania and the USA. In 2017, bg filtration purchased the company building in Renningen. In 2018, a new brand conquered the market with „bg textile air engineering“ and the company was recognised by Focus Business as one of the fastest growing companies in Germany in the field of mechanical and plant engineering.

Today, around 3,000 satisfied customers, over 1,000 systems worldwide and more than 10,000 individual components installed demonstrate bg filtration's expertise in a wide range of industries.

Quality as a leading feature

Quality has always been a top priority at bg filtration. Engineering and production under one roof, optimised processes and qualified personnel ensure a high standard of quality and, as part of our continuous quality cycle, any faults detected in production are immediately rectified by design. Every product is checked before delivery. Our filters are average over 30 years in use.

Save up to 25% on energy and maintenance costs. Conservation of resources through optimum functionality.

Each filter system is optimised for the application in terms of

  • of the product to be filtered
  • the product quantity
  • the delivery pressure
  • the pressure loss
  • the ambient conditions


In this way, we protect the environment and your wallet.

Sustainability is a matter close to our hearts

We therefore rely on regional partners with short delivery routes. Our suppliers are all located within a radius of just 300 kilometres.

80% of the material for our filter systems is sourced from within a radius of just 50 kilometres. We avoid long delivery routes, thereby strengthening the regional economy and reducing our ecological footprint.
