Joint development with our customer Schmersal

Schmersal, a Wuppertal-based company, approached us to enquire about the extent to which we would be interested in collaborating on a joint project.

project team has developed an FFP2 standard compliant respiratory mask. An FFP3 standard-compliant mask is within reach and is currently being tested before the mask can be marketed. The appropriate seal for the filters and the face had to be developed for this mask, the design and filter technology for which has been developed by Schmersal and other partners.In a challenging but highly productive collaborative project,we produced samples, working in close consultation with Schmersal. Using agile project management methodology, two seals were developed that meet the exacting demands of a high-quality respiratory mask. Series production will start shortly and soon the mask will be rolled out into health markets and into the public sector and companies. However, it can also be used in applications that existed before the advent of the coronavirus crisis. Improved wearing comfort, its light weight and scarcely discernible breathing resistance make it possible for users to wear the mark for a considerably longer period of time than conventional masks. We are delighted with the fantastic cooperation that has come about from the crisis, showing that something verypositive can emerge even in these challenging times.


The standard for masks is defined in DGUV Regulation 112-190. According to this, FFP3 masks may be used with pollutant concentrations up to 30 times the Threshold Limit Value (TLV).The total leakage may not exceed 2 % and it mustbe capable of filtering at least 99% of pollutants out of the air.Typical applications for an FFP3 mask include handling heavy metals, hardwood, brake dust, substances and pathogens, such as viruses, bacteria and fungal spores, as well as stainless steel welding.The Robert Koch Institute (RKI) recommends FFP2 and FFP3 masks for the treatment and care of patients with a SARS-CoV-2 infection.
