Invasive plant life can foul propellers, jam impellors and cause bilge pump failure.
The company says at the heart of the new compressor is a compact permanent magnet motor, with a central rotor suspended on self-stabilising air foil bearings, with precision balanced titanium impellors mounted at each end of the rotor.
The innovation has applications in propulsion (impellors, propellers, vanes), industrial processing (combustors, casting forms, metal filtration), medical devices, hot structures (thermal protection systems), RF/optical systems (mirror backings, apertures), microeiectromechanical systems (MEMS) and semiconductor processing.
