Cummins DuPont and 3M to defeat Coronavirus
Cummins DuPont and 3M: a trio of excellence combining forces for masks and respirators. When technology, albeit with different applications, is working together to stem the pandemic. Let’s start with the deal with DuPont (here DuPont Clean Technologies IsoTherming).
“The need for the masks has skyrocketed in recent weeks due to the global pandemic, and Cummins will use its NanoNet® Media to help answer that need. Cummins’ NanoNet® and NanoForce® Media technology, which uses DuPont’s Hybrid Membrane Technology (HMT), can typically be found in air, fuel and lube filtration products used in heavy-duty diesel engines to prevent long-term engine wear, but also can be used in the N95 respirator masks worn by healthcare professionals to filter harmful airborne particles that can spread COVID-19. The N95 designation means the respirator can block at least 95 percent of particles from entering the wearer’s nose and mouth. When Cummins’ NanoNet® Media was tested using an industry standard testing method, it exceeded the performance requirements for N95 designation. Cummins’ manufacturing facilities have since provided media samples to mask manufacturers across the globe to test its effectiveness. The first mask prototypes using Cummins’ donated media were assembled by University of Minnesota teams in March as part of an initiative to provide masks to M Health Fairview and other Minneapolis-based healthcare systems.
Masks with 3M
Cummins has reached an agreement with 3M to manufacture high efficiency particulate filters for use in 3M’s Powered Air Purifying Respirators, or PAPRs. Powered air purifying respirators (PAPRs) are an important piece of equipment for front-line healthcare workers responding to the COVID-19 pandemic. PAPRs use a battery-powered blower that sends filtered air into a hood or head top that covers the wearer’s head or face; and can provide increased levels of respiratory protection, especially for critical healthcare situations such as aerosol generating procedures. PAPRs may also be more comfortable to wear for those who need respiratory protection for long periods of time. The partnership has the potential to more than double the current production of filters for 3M’s PAPRs. The additional filters are needed as 3M has ramped up production of PAPRs to meet a surge in demand for personal protective equipment due to the COVID-19 outbreak.”
