Abstract: A container configured to establish an air flow curtain at an open end thereof is provided. The container includes a housing defining an internal volume with opposed five mutually perpendicular walls and an open end allowing access to the internal volume. A heater and a fan are disposed within the housing. An assembly is removably positioned within the internal volume of the housing and configured to be removed from the internal volume in a single motion without any external tools, the assembly comprises five mutually perpendicular walls and an open end allowing access to an internal volume within the assembly. When the assembly is positioned within the housing, a first plenum is defined within a space between the rear wall of the assembly and the rear wall of the housing, and a second plenum in fluid communication with the first plenum is defined within a space between the lower wall of the assembly and the rear wall of the housing.
