ABSTRACT:
A portable hot air circulator comprises concentrically mounted cylindrical members, the inner member being closed at its upper end to form a cup-like structure designed to mount over a conventional liquid fuel heater in closely-spaced relation. Air is forced downwardly through an annular passageway between the cylindrical members by a fan mounted through the top of the outer cylindrical member which is closed to form a plenum space between the tops of the concentric cylinder members. The fan is shielded by a louvered hood member, and spacer clips accomodate the mounting over the liquid fuel heater.
