A sealed vapor proof housing assembly in combination with a system for isolating an electrical device from the ambient atmosphere comprising a casing having a removable door to provide access to the interior of the casing, a first multiple number of heat exchange fins projecting from the casing into the atmosphere, a second multiple number of heat exchange fins projecting from the casing within the interior thereof for transferring heat from the interior to the ambient atmosphere, a sleeve liner disposed within the casing contiguous to the interior fins for forming a compartment with the liner having open ends spaced from the door and rear end of the casing. A fan is mounted on the liner for circulating air in a closed circulating pattern in intimate contact with the interior fins. Air is pumped into the casing through a one way valve and a pressure switch is electrically coupled to the fan and a power source for disabling the fan in response to a leak in the casing.
