Every Trane QF130V Inline Ventilator is placed with high-quality components. Each helps ensure that you can count on the ventilator to deliver fresh air, time after time. Today’s homes are better insulated and tightly sealed to save energy. This prevents a number of home odors (cooking smells, pet odors, paint or new carpet fumes) from escaping. QF130V Inline Ventilator helps these fumes and odors to dissipate by bringing fresher outdoor air into your home.
