About Us

Witten Vent was established in the 1970’s by A.F. Witten, a civil engineer and business entrepreneur. His uniquely designed plastic Automatic Vents are used in crawl space foundations, and are temperature controlled to open and close automatically. They are sold throughout the U.S.A.to a network of dealers and distributors.

In the early 1990’s, his son Erik expanded the foundation vent line to add aluminum and several new plastic manual vents, including the Jumbo model, each available in a variety of colors, with innovative packaging, and special carton sizes to fit customer needs.
