Abstract
Air filtration devices and systems are provided to filter conditioned air after air exits an air conditioner module located on a ground support equipment unit but prior to entering a grounded aircraft. Disclosed embodiments include a system with the air filtration unit located along a hose originating from an aircraft ground support unit and a system with the air filtration unit located along a hose originating from an aircraft. Certain embodiments of the air filtration unit include a diffuser, which is configured to couple to a filter and direct air through the filter during operation.
Claims19
A system comprising:
- an air filtration device for use with a grounded aircraft system, the air filtration device comprising:
- a housing configured to receive conditioned air and to output the conditioned air to an aircraft, the housing comprising a first end configured to removably attach to a first hose to receive the conditioned air and a second end configured to removably attach to a second hose to output the conditioned air;
- a filter removably secured inside the housing and configured to filter the conditioned air flowing through the housing between the first end and the second end;
- and
- a diffuser removably secured inside the housing and configured to direct airflow toward a periphery of the filter.
A system comprising:
- a ground support equipment unit comprising an air conditioning module configured to output conditioned air to an aircraft;
- and
- an air filtration device configured to receive and to filter the conditioned air, the air filtration device comprising:
- a body comprising a first end configured to receive the conditioned air from the air conditioning module and a second end configured to output the conditioned air to the aircraft;
- and
- a filter removably secured inside the body and configured to filter air flowing through the air filtration device between the first end and the second end.
An air filtration device for use with a grounded aircraft system comprising:
- a body comprising a tapered first end configured to removably attach to a first hose to facilitate fluid communication between the air filtration device and a ground support equipment unit, and a second end configured to engage a connector that is configured to removably attach to a second hose to facilitate fluid communication between the air filtration device and an aircraft;
- a filter removably secured inside the body and configured to filter air flowing through the air filtration device;
- and
- a diffuser removably secured inside the body, the diffuser including a tapered edge configured to cooperate with the tapered first end of the body to direct airflow toward an exterior surface of the filter.
