The QC STL PRO 1.5 is a new, energy saving model of the quiet whole house fans. It is the quietest of all the Stealth Pro fans, uses much less electricity and is perfect for bedrooms. Like our other smaller models, these work great as part of a multi-fan, multi-room system.  One STL PRO 1.5 can be installed in each of your occupied bedrooms (with attic space above). In a typical installation we would include 1 STL PRO 1.5 per bedroom and one of our larger fans (STL 4.8, 5.5, 6.5) in a central hallway. (Covers 750 sq ft)
