We have a variety of cutting-edge plants, punches and robotic-supported presses. Extremely short and efficient communication channels enable us to ensure individual planning and implementation in close cooperation with our customers.

Mouth and nose protection masks (SONO MN)

ATTENTION: Due to major public-sector contracts, the aim of which is to distribute our product within Germany in such a way that the supply of our health care system is ensured in the best possible way, a large part of our production capacity is virtually sold out.

IMPORTANT: Our oronasal protection masks are not certified according to FFP2 standard.
Currently, we only have a special approval from the Federal Institute for Drugs and Medical Devices (BfArM) for use in the medical field.
Unfortunately, a delivery to non-medical areas is therefore not possible.

Furthermore, due to the extremely high demand, we apologize for the delays in processing your requests.

For all these reasons we are forced to process only requests for at least 10,000 masks.

Their protective effect was confirmed not only by the BfArM but also by hygiene doctors for use during the corona pandemic from nearby hospitals.

Motivation:

We are an automotive supplier of acoustic materials, primarily for VW, Audi, BMW and Daimler, and as a medium-sized family-owned company. For years we have been producing our own microfibre fleece made of polypropylene. We meet the test standards for passenger compartments of BMW, Mercedes and the VW Group with our materials and millions of our products are in these vehicles.

Due to the standstill of our customers, production capacities are available.

It was and is our concern to use our meltblown plant capacity in the common fight against the COVID19 virus. This requires speed and pragmatism. 


Scope of delivery:

Due to the short product development time (start: 20.03.2020), we can currently only deliver our oronasal protection masks as a "kit".

The scope of delivery consists of filter mask, self-adhesive nose clip, elastic band and assembly instructions.
Handling: (Instructions for use sonoMN as video and assembly instructions as PDF)

We apologise for any shortcomings in the first production batches. We are working with priority and absolute pressure to optimize the product and maximize capacity.

The masks are sold as smallest lot size of 10.000 pieces in cartons on one-way pallets. Smaller lot sizes are unfortunately no longer possible at present.

Our technologies – for customized solutions

The THL technology (Tailored Heavy Layer), which we use for making sound insulation of PUR foam and heavy foils as weight and function optimized as possible, is a very good example for customized efficiency. After the first series application in the VW Passat, the next series application is currently being developed.

Our products – virtuosos in application

The DFA Bielefeld GmbH offers a wide variety of products and services:

The following exemplary components are used at various parts of the automotive sector, such as the end-wall region (inside, outside), but they can now be found in almost all interior areas as well. The materials and component properties are also very different. They are used for airborne sound absorption and airborne sound insulation.

SONOZORB - best absorption, lowest weight

SONOZORB is a brand name of our partner GDC Inc. in Goshen, Indiana. Together, we are able to offer absorber-fleece produced by a melt-blown process on different continents. Under the name SONOZORB B. we produce different variants exclusively for the European market.

Meanwhile, our product has been released for many OEMs and first Tier customers and is used for series production in various areas (exterior and interior). All details can be received on demand at one of our OEM sales colleagues or our specialists.
