DFT: Certification and Patents

The quality of our products and services,and our commitment to workplace safety and environmental protection are our priorities when developing and manufacturing our air filtration and cleaning systems. Consequently – and to safeguard our customers - we operate a Quality Management System that is regularly audited and certified to International Standards.

Furthermore, over the past few decades, our product development has led to the registration of patent applications. Something that emphasises the relevance of our products in their fields of application.

Our QM Certificate to ISO 9001:2015 and a selection of our registered patents are available for download here.
