A Little History

Established in 1927 near Rouen, France, Aoustin’s growth first expanded within the petrochemical industry. Since the 1960’s, Aoustin Mixer  filters have been installed for phosphoric acid production in over 90 locations worldwide. They provide the largest range of active filtration area, ranging from 9 m² to 250 m² (96 – 2690 ft²). Thanks to its unique design and build, Aoustin table filters have proven to have the most operating flexibility with the lowest operating costs.

We are not the Aoustin Mixer OEM, however  we do service their products.
