Custom fabricated 24" high velocity combination air eliminator / dirt separator for the hot water system and custom fabricated 30" high velocity air / dirt for chilled water.  When installed in 2005, the 30" was the largest combination unit ever built.  That has since been surpassed with 36" combination units installed at Penn State University and The University of Missouri.
