Completed TRL 5 (started at 4, targeting 5)
This Compact High Efficiency Self-Cleaning Dust Filter for Martian Air will be effective in removing dust particles in air that can adversely affect the performance of equipment, such as air compressors and oxygen generators. The filter consists of two parts. The first stage is a rotating separator that will remove the larger dust particles aerodynamically and mechanically from the gas flow. The second part is an electrostatic separator that will charge up the smaller dust particles and remove them from the gas flow.
The technology could provide 1) increased dust filtration efficiency, 2) filtration of particles over a wide size range (including fines) in a single compact device, and 3) and possibly a simple self-cleaning capability.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
