About Us

Schoonover was established in 1963 as a manufacturer's representative for technical products. Today, Schoonover specializes in representing companies/products for high vacuum equipment, leak detection, high temperature furnaces, fine filtration filters, and cryogenic cooling equipment. In 2006, our products division, Apex Vacuum, began selling mass flow & vacuum products. Our aim was to not only to  provide the technical equipment customers needed but delivered it with engineering expertise to meet customer applications. In 2020, Apex Brands was introduced to provide products and services outside of the Apex core product line-up that could benefit from our expertise and service to the customer.

At Schoonover, if we get the engineering and technical details correct, the sales tend to follow! Customer service is at our core and what makes our customer experience unique!
