Recognizing an opportunity and taking it. That entrepreneurial spirit is how IVI, Inc., got its start in 1993. Changing environmental attitudes led to The Clean Air Act of 1990, sparking the realization that manufacturers needed to install or upgrade industrial ventilation systems to comply with new regulations. And this industrial ventilation manufacturer was born.

Today, that entrepreneurial spirit is part of its DNA, helping them see opportunities for their customers. In industrial ventilation and metal fabrication, they find ways to do what others can’t or won’t. Using the latest technology, IVI is driven to solve your dust collection and metal fab problems.
