Quality Management

Quality starts with know-how

Guaranteed quality is the decisive criterion when it comes to delivering solutions for challenging filtration tasks. Whether it is the protection of expensive engines, the safeguarding of the environment or the well-being of all living creatures – in every step of our operations we are focussing on the uncompromising quality of our systems. This is the only way we can meet the requirements of our environmental management system in accordance with ISO 14001 and make a sustainable contribution to the protection of valuable resources such as water, energy and raw materials.

Our quality is secured by a zero defect strategy and our quality management system which has been established throughout the entire company. Our quality management system was designed according to international standards and is regularly audited by Lloyd’s Register Deutschland GmbH, which has held
ISO 9001 certification since 1994, ISO 14001 certification since 2004 and ISO 45001 since 2011.

No product leaves our company without a comprehensive final acceptance inspection, which means that every BOLLFILTER will be a longtime and reliable partner for many years – guaranteed. A deliberately high level of vertical integration including welding, mechanical processing, filter element production, final assembly, plant engineering and construction also gives us complete control over all the factors which influence quality.

In numerous external audits by various companies, the process of continuous improvement is measured and developed further.
