We are mask professionals with ambition and know-how

We have been making mouth and nose masks since the beginning of the corona pandemic.
It all started on March 20th, 2020 when the melt-blown systems were switched to masks and nose clips were made. Mask kits were the first to be produced and as such were delivered in large quantities with a special permit from the BfArM.

We now have certificates in accordance with EN 14683 for Type II (Sono E5), Type IIR (Sono E6) and, most recently, an EN 14683 Type II certificate for the unique antiviral AND certified mask (Sono E3). This everyday mask is particularly suitable for users who are not medically trained, as 99.9% of the viruses on the outside of the mask are killed after one hour! The special fleece material is certified for its anti-viral and antibacterial effect, and approval according to the biocide regulation is also available.

Behind it is DFA's own meltblown fleece, which filters out > = 98% of the bacteria.

All DFA respiratory masks have a special design based on FFP masks, so that the Sono masks fit much closer to the face and thus offer the wearer and the environment a significantly higher level of protection against viruses than the classic mouth and nose protective masks with folds. The antiviral E3 mask thus offers the best possible protection for the pandemic while at the same time being very comfortable to wear and low breathing resistance.

A certification according to EN149 is currently also being worked on.

DFA produces its own meltblown fleece for all masks on fleece systems. An additionally procured system was funded by the Federal Ministry for Economic Affairs and Energy.

The masks can be ordered directly online here.

The DFA Automotive GmbH in Goslar

Our expertise in bitumen, plastics, and aluminum, as well as our many years of experience with all the relevant procedures, are among our greatest strengths, which we are able to bring to optimum effect thanks to our excellent technical facilities.
Our ultramodern in-house systems engineering is based on a sound understanding of stamping technology and punching tools. Our in-house adhesive development and production is tailored to our finishing processes, and our inline compounding of formulas allows us to directly process the finished product as part of a seamless procedure.
This allows for the successful development and production of even lighter damping and reinforcement sheets, with an even greater acoustic effect.
Our product range includes conventional single-layer sheets, which are either heat activated, self-adhesive, or magnetic, and thus ideally suited for sealing paint drain holes. Our multi-layer sound deadening products are magnetic and self-adhesive. We also produce aluminum-bitumen sandwich solutions and aluminum-plastic sandwich solutions, which are self-adhesive and suitable for body-in-white applications on oily sheet metal.
Our thermally expanding bitumen sheets, applied in body shop with constraint layer materials on body panels, is as powerful as our special sealants, which are self-adhesive and used to seal paint drain holes in the assembly.
We provide reinforcement materials as optimal, self-adhesive sheets, ideal for body-in-white application on oily sheet metal and for applications in ribbed e-coded panels.
