Exclusive Durablade economizer damper design saves energy while
providing economical and reliable cooling. A sliding plate on the face
of the economizer controls the amount of outdoor air entering the
system. When the sliding plate is closed, it provides a leakproof seal
which prevents ambient air from seeping in or conditioned air from
seeping out. It can be easily adjusted for 100% outdoor air or any
proportions of mixed air. Equipped with standard controls and 30%
barometric relief capabilities.
