A droplet bandpass filter and method of modifying droplet size distribution of a population of droplets suspended in a gas. Droplets suspended in a gas are flowed through a bandpass filter having a tortuous pathway which comprises at least one impactor region located at a position adjacent to a flow direction change. Larger droplets impact at the impactor region while smaller droplets remain suspended in the gas and flow in the first output direction. Other flow restrictors may advantageously be included in the tortuous pathway. The filter is particularly useful in delivering sterilant aerosols (e.g. peroxides) with reduced populations of large droplets.

A water collector assembly includes a diffuser assembly having a diffuser body. The diffuser body extends between an inlet duct and an outlet duct along a first axis. The diffuser body includes a first end wall extending from a second inlet duct end towards a first inlet duct end, a second end wall extending from a first outlet duct end towards a first inlet duct end, and a side wall extending between the first end wall and the second end wall.

A hood air intake and water separation system includes a first separation chamber having a first inlet fluidly coupled to a hood intake vent of the vehicle, a first outlet, and at least one first drain opening. The first separation chamber is configured to separate water and air ingested through the intake and direct the separated water through the at least one first drain opening and direct the separated air through the first outlet. A second separation chamber includes a second inlet fluidly coupled to the first separation chamber first outlet, a second outlet, and at least one second drain opening. A third chamber includes a third inlet fluidly coupled to the second separation chamber second outlet, and a third outlet. The first and second separation chambers are configured to direct ingested water away from an airpath to the engine.

An annular water removal system (AWRS) for an air cycle environmental control system (ECS) includes a line replaceable unit (LRU) configured to output air flow, and a water collector coupled to the LRU. The water collector includes an upper portion and a lower portion. The upper portion includes a coalescing unit having a collector inlet to receive the air flow and configured to coalesce moisture from the air flow output from the LRU. The lower portion includes a collection unit in fluid communication with the coalescing unit. The collection unit is configured to collect the moisture coalesced by the coalescing unit.

The invention relates to an aerosol separator for separating aerosols in a blow-by gas, which comprises at least one feed opening for feeding a blow-by gas provided with aerosols, an outlet opening for discharging a blow-by gas cleaned of aerosols, at least one outflow opening for releasing aerosols removed from the blow-by gas, and which is arranged between a flow path of the at least one feed opening and the outlet opening, and a plurality of projections for configuring the flow path running from the at least one feed opening to the outflow opening in a meandering manner, in order to decelerate the blow-by gas which enters the feed opening and which is provided with aerosols, in terms of its flow rate. The separator is characterized in that the projections in their end region, around which blow-by gas flows, have a portion with increasing projection width.

The filter device includes a supply air introducing part, a filter main body part and a discharge part. The supply air introducing part takes in an outside air. The filter main body part includes a ventilation pipe connected to the supply air introducing part to allow the outside air to flow through the ventilation pipe and a filter housing part being equipped with an outflow hole allowing the outside air to flow outside at a position higher than a position of the opening part of the ventilation pipe to separate, from the outside air, a liquid in a liquid state or a state close thereto. The liquid is taken in together with the outside air. The discharge part discharges at least the separated liquid from the filter main body part.
