Cummins and DuPont partner to supply critical material for N95 respirator masks

The first masks featuring the filter technology are being used as part of a project to supply masks to Minnesota’s M Health Fairview network

As the COVID-19 pandemic spreads across the globe, Cummins Inc. and DuPont are helping address the nation's shortage of N95 respirator masks. 

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 need for N95 masks has skyrocketed in recent weeks in response to the COVID-19 pandemic. Many of the world's leading mask manufacturers are in need of the critical materials to assemble the mask and are struggling to meet demand.

"Cummins is re-evaluating our supply base and manufacturing capabilities to identify how we can support our healthcare professionals who rely on critical personal protective equipment to do their jobs," said Amy Davis, Vice President of Cummins Filtration. "Our NanoNet Media can fill a key supply void and help address the mask shortage facing the United States and other countries around the world."

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. 

As the COVID-19 outbreak escalated, the University of Minnesota realized their supply of N95 masks to protect healthcare workers would potentially run out in a matter of weeks. To address this challenge, a team of designers, engineers, chemists, surgeons, anesthesiologist and apparel and clothing experts from the University of Minnesota's Institute for Engineering in Medicine; Medical School; College of Design; College of Science and Engineering; and Center for Filtration Research Consortium (CFR) came together to address this projected shortage of critical personal protective equipment.

"The first thing we recognized from our experts in the Center for Filtration Research, who work directly with Cummins, is that not all filtration materials are created equal and that the Cummins material is an excellent alternative," said Jakub Tolar, Campus Health Officer and Medical School Dean at the University of Minnesota. 

"We are tremendously grateful for the generous donation from Cummins of their filtration materials toward our mask effort. Since the arrival of the filtration media, we have been able to make rapid progress, and we now believe we have several viable mask options, including both a disposable and re-usable option. These designs show real promise in keeping our healthcare workers safe should standard medical supplies of N95 masks no longer be available," continued Tolar.

The project also aims to provide open source instructions that other healthcare systems and groups can use to create their own respirator masks.

While DuPont's innovative and unique Hybrid Membrane Technology (HMT) is typically integrated with Cummins' synthetic fibers to protect sensitive engine components, it has multiple other applications that can include filtration media used in N95 respirator masks.

DuPont's Hybrid Membrane Technology goes beyond the limits of traditional semi-porous or nonwoven membranes for air and liquid filtration. Made using a proprietary spinning process, the hybrid technology materials are comprised of continuous sub-micron fibers. The end result is a "membrane-like" sheet structure that balances breathability and high filtration efficiency of particulates.

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.

Trail King Steerable Dolly Offers Better Maneuverability

Trail King recently updated the design of the steerable dolly with a front steer design. This new design allows for better maneuverability for a greater steering angle, tighter corners and less manual steering.  The dolly offers wireless manual steer and auto alignment after manual steer for an automatic self-centering function. Trail King has increased the hatbox rotation angle on this model with the ability to turn up to 65 degrees. The centralized grease port for turntable allows for easy upkeep and maintenance. This versatile dolly can be used with a Schnabel setup, replace standard wheel area for a steerable 13 axle configuration, or can be used in combination with a Jeep/Dolly for Bunk work.
