TECHNOLOGY TRANSFER OPPORTUNITY: Multi-Stage Filtration System (LEW-TOPS-93)

Innovators at NASA's Glenn Research Center have developed a unique multi-stage filtration system to collect a wide range of particle sizes with minimal filter changes. This breakthrough capability keeps high-efficiency media and devices from becoming overloaded with larger particles. Glenn's system uses an impactor filter to capture larger particle matter through inertial separation and impaction methods on collection surfaces. After becoming heavily loaded, this filter can be cleaned automatically through a unique feed system, thereby reducing maintenance costs. In this way, the device provides a pre-filter stage that protects the more critical stages of the filter system, thereby extending the life of high-efficiency particulate arresting (HEPA) filter systems that are designed to capture fine and ultrafine particles. In an effort to reduce maintenance even further, the fine-particle filter media is provided in a scroll mechanism that is advanced to successive clean sections as

needed. Highly sensitive filtration systems can be challenging to maintain and protect, so Glenn's system, which provides time and power savings offers great potential for commercial development.To express interest in this opportunity, please submit a license application through NASA’s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/LEW-TOPS-93If you have any questions, please e-mail NASA’s Technology Transfer Program at Agency-Patent-Licensing@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this SAM.gov notice and your preferred contact information.
