ABSTRACT:
The hygroscopic breather cap for a fluid such as a liquid petroleum tank in which air enters the bottom of an elongated cylinder, passes through a knitted fabric filter to remove dust particles, passes through a desiccant along the entire height of the cylinder to remove moisture, passes through a second knitted fabric filter to remove desiccant fines, and then passes into the opening of a standpipe for passage downwardly along the axis of the cylinder into the petroleum tank. A window may be provided in the top of the cylinder to view the condition of the desiccant, or alternatively, the body of the cylinder may be made transparent. A number of reduced strength areas may be provided at the bottom of the cylinder so that the effective size of the opening to the atmosphere may be selectively varied. A removable cap permits a recharging of the cylinder with desiccant.
