The AURA EXD is an automatic switchover system designed to provide a continuous supply of high purity gas for inlet pressures up to 210 bar. The integral EX1 line regulator provides consistent outlet pressures. AURA’s encapsulated seat design consolidates the numerous moving internal components of a standard regulator into one single piece, allowing for ease of maintenance and minimizing potential failure points. Protected by a 10-micron 360° filter, the encapsulated seat provides significantly more filtration of impurities than the standard pressed-in disk. The encapsulated seat also filters damaging particles from all inlet ports rather than just the pipeline port.

AURA’s proprietary machining process yields surface finishes of 4-25 Ra designed to reduce corrosion. The optional inlet purge or shutoff valve assemblies require minimal connections, reducing potential leak paths and internal volume.  With its minimal internal volume, the EXD allows less gas to be used while purging. The EXD’s regulators are assembled in a Class 100 clean room while the complete EXD assembly is 100% helium leak checked and cleaned for oxygen service.  Additionally, the EXD undergoes multiple flow and function tests to meet the harsh demands and rugged environments of any application worldwide. The AURA EXD allows for maximum flexibility and superior functionality as the engineer’s first choice for an uninterrupted supply of high purity gases.
