An oil recovery system for recovering oil from an air/oil mixture from a gas turbine engine, the oil recovery system including a first separator coupled to receive the air/oil mixture from an air/oil mixture source, wherein the first separator separates at least a portion of oil from the air/oil mixture and an ejector for drawing the air/oil mixture contained in the first separator into the ejector. The ejector combines the drawn air/oil mixture and the compressed air such that the resulting combined mixture of compressed air and drawn air/oil mixture has a lower temperature as compared to a temperature of the air/oil mixture contained in the first separator, and wherein the recovered oil is captured.

An air filter system for use as original equipment or conventional filter replacement in a building ventilation system includes multiple helical particle separator elements in a parallel array, each element configured to remove particles from a respective portion of contaminated inflowing air. The outflows from the separator elements are combined into a common clean air outflow which is delivered to the building ventilation system. A common waste receptable collects particles removed by the separator elements and is cooperatively connected to a scavenger air system that draws air through the array and the receptable and relocates them to a desired location. The separator element array may be housed in a filter system containing the main system fan arrangement that is configured to draw or force the airflow through the multiple particle separators.

A system, apparatus, and method are provided herein to remove water from air aboard an aircraft to permit use of dry air and discharge of water. A system for cooling electronic components of an aircraft includes: an air intake port defined in a forward facing surface of the aircraft; a flow path defined between the air intake port and an air exit port, where the flow path includes at least one bend of at least ninety degrees between the air intake port and the air exit port; and a low-pressure tap line intersecting the flow path proximate the at least one bend, where the low-pressure tap line is in fluidic communication with a water exit port defined in an upward-facing surface of the aircraft.

An improved skimmer separator system for separating cotton from an airstream is disclosed. Comprising the improved skimmer separator system comprises a main body, an elbow duct an elbow inlet, a drum wiper assembly, a hopper chamber. The main body housing internal components for separating cotton. The elbow duct positioned within the main body, configured to redirect the airstream from a substantially horizontal trajectory to a substantially vertical trajectory through the elbow inlet. A screen is positioned at an inner corner of the elbow duct to allow air to pass through while retaining cotton. The drum wiper assembly configured to scrape the screen to prevent cotton buildup. A skimmer chamber connected to the elbow duct via an elbow wiper outlet, configured to capture heavier materials. The hopper chamber connected to the elbow duct via an elbow lower outlet, configured to collect lighter cotton descending by gravity.

A dust collecting device is provided. The dust collecting device includes a particle separation component, an airflow output component and a particle collection component. One side of the particle separation component extends outward to form a first gas input portion, one end of the particle separation component extends outward to form a first gas output portion, and another end of the particle separation component extends outward to form a foreign matter outlet portion. One side of the airflow output component extends outward to form an airflow inlet portion, one end of the airflow output component extends outward to form a second gas output portion, and another end of the airflow output component extends outward to form a second gas input portion. The second gas output portion is connected to the first gas input portion. The particle collection component is connected to the foreign matter outlet portion.

A mist collection and separation assembly is disclosed for improved operability and maintainability. The assembly includes a rotor disposed concentrically within a housing and powered by an electrical motor that generates suction, drawing mist from a target environment into a rotor interior cavity. The mist impacts a rotor surface and reverses direction, causing liquid and potential particulate content to separate due to inertia. Separated matter drains through designated housing ports, while clean air is exhausted. The assembly operates filter-free, reducing maintenance and cost. Vertical orientation enhances separation via gravity, and grooved rotor surfaces facilitate drainage. Wetted internal housing surfaces enable passive self-cleaning through molecular adhesion of submicron particles. Optional removable filters may be included for improved reliability.
