Gas/Liquid Separators Brand History

Wright-Austin Type S Separator 1934

Our cyclonic separators are fabricated by two manufacturers, one located within the USA and the other in Reynosa Mexico.

The basis for our product offering are the Wright-Austin™ gas liquid separator, exhaust heads and float drain trap designs.  Wright-Austin was established in 1894 and pioneered the cyclone separator design. Hayward Filtration acquired Wright-Austin in 1996. 

After the acquisition by Hayward, the Wright-Austin facility in Michigan was closed and manufacturing operations transferred to New Jersey.  Some key personnel  from Wright-Austin did not want to make the move to New Jersey and instead decided to remain in Michigan and form another separator manufacturing company called Circle-S.

In 2005 Eaton Hydraulics LLC (Filtration Division) acquired Hayward Filtration and the Wright-Austin product line.  After Eaton's acquisition of Hayward, they decided to maintain corporate headquarters with design and engineering in New Jersey, but transferred manufacturing to Mexico.  Although Eaton has fabrication capabilities within the USA and other countries, most of the Wright-Austin products are manufactured in Mexico with the castings for their iron products originating from foundries in China.

Circle-S has one manufacturing location in Monroe Michigan and you will notice that their drawings and datasheets are often identical to the Eaton/Wright-Austin datasheets because they both utilize the same "original" Wright-Austin design.
