Product features
Fresh air inlet
A knock-out for outside air, so the unit can ventilate as well as cool.
Two return air modes
Return air from the back or from underneath — the duct layout decides, not the unit.
Constant air flow
The fan holds its set air volume as filters load and ducts vary (on supporting models).
