Low-cost helix MICRA filters for industrial dust capture
Helix MICRA filters, developed for microgravity use, offer a low-cost, energy-efficient solution for capturing industrial dusts. With >99% efficiency and low pressure drop, these filters are ideal for mechanized sampling and pulverizing processes.
Overview
Helix MICRA filters provide an efficient approach to industrial dust capture, targeting microscale dusts generated by mechanized sampling and pulverizing processes that can pose health risks if inhaled and degrade air quality. The patented design is intended to deliver energy efficiency and noise-free operation for industrial use.
Technical specifications
- Additive Manufacturing: The filters are created using a low-cost additive manufacturing process.
- Helical Passageways: Features parallel series of helical passageways designed for minimal pressure drop (<150 Pa) that maintains efficiency despite particulate capture.
- Filtration Efficiency: Capable of capturing over 99% of particulate matter ranging from 1–1000 μm in size.
- Long-Term Use: The filter design is intended to prevent degradation over time, enabling extended use with minimal maintenance.
Technology readiness level
The Helix MICRA filters have achieved a Technology Readiness Level of 8, indicating demonstration in operational environments. A research team at Rice University is working to validate and customize the technology for specific industrial applications. Future plans include on-site testing and potential licensing for local fabrication.
