Airfield systems, devices, and methods

An airfield generator comprising:

• a motor configured to drive blower;
• an internal cavity configured to convey an airflow;
• and
• a cooling system comprising:
• a first heat exchange positioned around the motor of the airfield generator;
• a second heat exchange associated with the internal cavity of the airfield generator, wherein the first heat exchange is in fluid communication with the second heat exchange;
• and
• a pump configured to circulate a fluid between the first heat exchange and the second heat exchange,
• wherein the first heat exchange is configured to transfer heat from the motor of the airfield generator to the fluid, and the second heat exchange is configured to transfer heat from the fluid to a portion of the airflow in the internal cavity of the airfield generator.

A filter for an airfield generator, the filter comprising:

• an elongate body extending from a proximal end to a terminal end opposite the proximal end, the body comprising a polygonal shape having sides and vertices, the sides extending from the proximal end to the terminal end between the vertices of the polygonal shape, the body further comprising a longitudinal length between the proximal end and the terminal end;
• a first end opening at the proximal end of the body;
• a second end opening at the terminal end of the body;
• one or more filters on the sides of the body, wherein the one or more filters extend along at least a portion of the length of the body;
• and
• wherein the body is configured to draw-in air through the first end opening and through the second end opening and to exhaust the drawn-in air out of the body through the one or more filtering portions on the sides of the body, wherein the one or more filtering portions are configured to filter the air passing through the one or more filtering portions.
