Local production
We are proud to produce the full range of DeltriSafe and DeltriGex masks at our Fleurus site.
Welcoming two manufacturing lines until June 2020, our Walloon site has doubled its production capacity and is now equipped with four functional lines exclusively dedicated to citizen and surgical masks.

Our history
Bounce back, innovate and adapt, these are the strengths of our teams.
For more than 50 years, Deltrian has been manufacturing air filters that improve the quality of the air we breathe. Thanks to the work and dedication of our teams, we provide the best filters to our customers. Our air filters are capable of filtering the smallest particles of polluted air and provide clean air.
In our industry, we aspire to be a leading player, to lead change, to innovate and of course to grow. But above all, we want to achieve this goal by making responsible choices and taking decisions that take into account not only today's data, but also their potential impact on tomorrow.
In the face of the COVID-19 pandemic, we were shocked and amazed to learn that our hospitals, doctors, nurses and citizens were running out of supplies while the fight to contain the virus is hard and has only just begun. We have decided to get personally involved by proposing a concrete, rapid and sustainable solution for the manufacturing and supply of quality surgical masks.
As such, Deltrian has applied to support the Walloon Region's industrial project aimed at encouraging the local production of FFP surgical masks, because today we must think about the post-Coronavirus era and be able to be resilient.
Our DNA as a producer of quality filters, the hard work and ambition of the Walloon Region's teams, who work hard, as well as the seriousness of the industrial project, motivate us to respond now.
Deltrian can rely on its experience as a producer of filters, on the motivation of all its teams, to be able to manufacture very quickly, at Fleurus, millions of respiratory masks and thus help the community, our hospitals and our customers in the crisis we are experiencing.
