Hydro-Pac was founded in 1972 in response to an emerging market for compressors and pumps capable of achieving high pressures. Since then we have manufactured thousands of units for a variety of locations throughout the world. Our standard machines include gas compressors, liquid pumps and pressure vessels.

Our headquarters is located in Northwestern Pennsylvania at a 28,000 square foot facility. This facility consists of approximately 20,000 square feet of manufacturing space and 8,000 square feet of office space. From this facility, we sell, manufacture and service all of our equipment world-wide.

Hydro-Pac also has a sister company, Nihon Hydro-Pac, with offices in Tokyo and Gifu, Japan. Nihon Hydro-Pac is responsible for distribution, sales and service for all Hydro-Pac equipment in Japan. For more information http://www.nihon-hydropac.com/ or email sales@nihon-hydropac.com
