QuietCool QC TRI PRO 2.5

The new QC TRI PRO 2.5 is quickly becoming the most popular model of fan. The Trident Pro Series 2.5 provides 2,304 CFM, operates very quietly and is a great product for individual bedrooms. This fan is a single speed whole house fan. Like our other smaller models, these work great as part of a multi-fan, multi-room system.  One of these fans can be installed in each of your occupied bedrooms (with attic space above). In a typical installation we would include 1 TRI PRO 1.5 per bedroom and one of our larger fans (TRI PRO 4.8, 5.5, 6.5) in a central hallway. (Covers 1,150 sq ft)
