Who We Are

Founded in 1966 by French engineers Gobil and Champanier, GOSAG SAU began an era of innovation in separation and classification technologies. Since its beginnings in Avilés (Asturias), where it started manufacturing under license MOGENSEN screeners, sand washers, vibratory distributors and densimetric separation tables, the company has been a reference for quality and technological progress.

The acquisition of GOSAG SAU by Allgaier in 2003 marked a new phase of expansion and technological advancement, strengthening our position on the world market.

The merger with JOEST in 2023 and the transition to MOGENSEN Spain not only marks a union of local expertise with global reach, but also represents a milestone in our evolution, combining extensive know-how and technological edge.

We continually strive to exceed industry standards and develop advanced technologies that respond to current and future challenges. Our passion for excellence and our commitment to sustainability and leadership in separation and sorting provide effective solutions.
