Airfield systems, devices, and methods

An airfield generator comprising:

• a housing comprising:
• a base comprising a first air intake, a second air intake, a third air intake, and a first internal cavity providing an air passage through the base;
• a first filter in the first internal cavity and configured to filter air entering the base from the second air intake and the third air intake;
• and
• a first outlet comprising an upwardly directed opening configured to generate an airfield, the first outlet being in fluid communication with the air passage of the base;
• a filter system housing configured to be coupled to the first air intake, the filter system housing comprising:
• a fourth air intake, a second outlet in fluid communication with the first air intake, and a second internal cavity providing an air passage through the filter system housing between the fourth air intake and the second outlet;
• and
• a second filter in the second internal cavity, the second filter configured to filter air passing through the filter system housing;
• a fan comprising a motor that is positioned at least partially within the first internal cavity, the fan being configured to:
• generate a first air flow from an ambient environment surrounding the airfield generator into the second air intake and the third air intake, through the first filter and the base;
• generate a second air flow from the ambient environment surrounding the airfield generator into the fourth air intake, through the filter system housing and the base;
• and
• wherein the first air flow and the second airflow mix in the first internal cavity to form a combined air flow, and the fan is configured to force the combined air flow out of the airfield generator via the first outlet thereby generating an airfield;
• and
• a cooling system configured to cool the motor, the cooling system comprising a first heat exchange associated with the motor, a second heat exchange associated with the first internal cavity, and a pump;
• wherein the first heat exchange is in fluid communication with the second heat exchange, and the pump is configured to circulate a fluid between the first heat exchange and the second heat exchange, and
• wherein the first heat exchange is configured to transfer heat from the motor to the fluid, and the second heat exchange is configured to transfer heat from the fluid to a portion of the combined air flow in the first internal cavity;
• wherein the airfield generated by the first outlet provides a barrier between a first side of the airfield and a second side of the airfield;
• and
• wherein the airfield is configured to inhibit passage of aerosol particle through the airfield from the first side of the airfield to the second side of the airfield.
