BROAN QT Series bath fans offer the rare combination of power and extremely quiet operation. A bath fan needn’t call attention to itself, especially when you don’t want it to overpower the design of a bath or powder room. More important, it shouldn’t call attention to itself when it’s working. So BROAN developed the QT Series to provide their quietest bath fans yet. The BROAN QTXE110 Ultra Silent Bath Fan simply does its job quietly, in every sense of the word.
