Abstract
An acoustic filter in which the internal flow element is acoustically decoupled from the surrounding vessel to lower noise emanating from the filter by securing the filter bulkheads to the internal flow element rather than welding to the vessel wall. The connection of the bulkhead to the vessel is mechanically discontinuous and reduced vibration transmission to the vessel from the internal flow element is obtained. The internal flow element is a unitary body with channels which are readily formed. The filter vessel is better able to move relative to the bulkheads in response to pressure and temperature changes with the invention design.
