Abstract: One or more techniques and/or systems are disclosed for a fluid inlet that mitigates uptake of undesired debris into fluid transport system. A fluid inlet can direct fluid toward one or more fluid inlets, and debris entrained in the fluid may bypass the fluid inlet(s). The fluid inlet can be used to mitigate uptake of debris into a fluid transport system, when placed in the path of fluid flow. A shape of the fluid inlet can be configured to direct fluid flow into the fluid inlet(s), while the shape allows debris entrained in the fluid to flow past the fluid inlet(s).

Abstract: A cyclonic chamber for use in air filtration devices. The chamber includes an apex opposite a base with sidewalls extending therebetween. The cyclonic chamber is preferably parabolic in cross-section or tubular with a hemi-spherical cap. The base contains an outflow passage and a conical filter extending therefrom. An inflow passage is provided proximate the apex. The inflow and outflow passages are parallel but not aligned. The chamber interior is smooth. The smooth interior and offset relationship of the inflow and outflow passages causes air to take a cyclonic path between the inflow passage and the filter. Debris in the airstream is pushed outward—away from the filter—by centripetal force. Eddies form proximate the base. Debris escapes the airstream there, where it either remains or, depending upon the chamber's orientation relative to gravity, falls back into the airflow where it is again directed away from the filter.

Abstract: A snow filter for an airplane cabin air supply system is provided with a coned inlet screen which allows some air to pass through and some snow to be retained. The coned configuration diverts much of the air and snow toward a downstream conical retaining and collecting screen positioned toward the outlet of the snow filter. Snow is retained and collected at this point while air is able to pass through the screen. Downstream of the coned inlet screen and upstream of the conical retaining and collecting screen is an open air flow mid-portion that enables tortuous flow of air as the snow is directed toward the conical retaining and collecting screen in an annular collection volume. The outlet of the snow filter is provided with a contact sleeve that allows the snow filter to be fittingly received by a surrounding corresponding air duct. Thus a snow filter is provided that effectively separates snow from a flow of air while maintaining a clog-free path.

There can be more than one venturi cell depending upon the degree of purification required for the refrigerant gas.
