Penn State is one of our largest university customers with more than 90 installed across campus. The first was several years ago, which led to the Spirovent® being considered as a key component of a campus wide water quality improvement project for the HVAC systems. PSU is also the home of one of only two of the largest Spirovents ever built worldwide. The custom high velocity 36" air eliminator and dirt separator is installed in the West Chilled Water plant and designed to handle 27,000 GPM.
