Welch by Gardner Denver

Welch, formerly Ilmvac, is the union of two prominent names in vacuum technology: Welch and Ilmvac. 
Since its establishment in 1852, Welch has been supplying innovative vacuum pumps to laboratories, industrial manufacturers and educational institutions around the world. This extensive experience has allowed Welch to develop optimal vacuum solutions for a diverse range of applications.
Ilmvac was founded in 1947 as a producer of a complete range of laboratory equipment.  Later, the company elected to concentrate its expertise in the realm of scientific vacuum technology, bringing numerous advances to the world market.
The merger of these two respected companies and our continued investment in research and development allow us to offer you an even stronger, more advanced portfolio of vacuum solutions.
