Traditional styles for more conservative budgets. For the bath that's not used everyday you may not have to be as concerned about energy efficiency. The QTR line was designed to satify that need. The fan and fan light models are still among the quietest products in their category, but feature bright incandescent rather than fluorescent lighting. Since they're a perfect match to the QTRE line, they're an ideal design solution for any bath or powder room.Extremely quiet operation Designed for easy installation Motor engineered for continuous operation 4 Duct connector Warranty: Limited Three YearAmperage: 0.9 CFM: 110 Grille Length: 13 Grille Width: 13 GrilleFinish: White Polymeric Heater Included: No Housing Depth: 7-5 8 Housing Height: 7-3 4 Housing Length: 10-3 4 Housing Width: 10-1 2, 11-1 4 Humidity Sensing: No Light Included: No Max Area Bathroom: 100 Motion Sensing: No Series: Ultra Silent QT Sones: 1.5 UL Listed: Yes Weight: 12.4
