A fluid intake comprising a first duct, a second duct and a particle separation spinner defining an interface between the first duct and the second duct. The spinner comprises flow passages passing from a first duct side of the spinner to a second duct side of the spinner and splitter bodies separating the flow passages. The flow passages and splitter bodies are arranged in a thread-like screw manner about the spinner. In use, the spinner is spun about its longitudinal axis such that the splitter bodies and flow passages have a component of movement towards a main travel direction of a fluid flow incident towards the spinner from the first duct. The splitter bodies are arranged such that they oblige fluid in the fluid flow to follow a convoluted path if it is to pass from the first duct to the second duct via the flow passages. |
