Abstract
The combination breather-drain is designed to be disposed in the bottom of an explosion proof housing to facilitate the drainage of moisture from the housing by gravity while simultaneously providing an atmospheric communication with the interior of the housing through a separate passage. The passage for the drainage of moisture is defined by a loose threaded connection between a hollow cylindrical plug and a fitting secured to the bottom of the housing. The threaded connection is so dimensioned as to prevent the passage of a flame through the threaded connection. A plurality of baffles or a solid threaded plug are provided in the interior of the hollow cylindrical plug to provide an air passage so dimensioned as to prevent the passage of the flame therethrough.
