Abstract
A method and apparatus for venting the seal air pressure within an isolated system so as to obtain a relatively small, in the range of 4 to 8 inches water gauge more or less, pressure differential across the isolation dampers. This small pressure differential is desired so as to reduce the load against which the dampers must operate thereby permitting a more economical design of such dampers.
