How-To Articles


    As the global leader in residential indoor air quality, Broan designs progressive and innovative products to provide maximum comfort for any household. Broan ULTRA GREEN™ fans are engineered to be quiet, reliable and most of all, efficient. The XB50 is a single-speed bathroom exhaust fan that operates below 0.3 sones, making it one of the quietest fans on the market. Ideal for both spot ventilation in humid bathrooms and continuous ventilation applications, the XB50 is a flexible ventilation solution while remaining incredibly energy-efficient.
  • Energy Efficient
  • Broan's ULTRA GREEN™ series bath fans feature ULTRASMART™ DC motor and control technology. The XB50 operates almost ten times more efficient than ENERGY STARŪ requirements.
  • Quiet Operation
  • Featuring ULTRASilent™ technology, the XB50 operates at less than 0.3 sones - the lowest sound rating attainable. The XB50 is so quiet, you may not even notice it running.
  • Simple Installation
  • With Broan's ULTRAQuick™ technology, the XB50 features a telescoping mounting frame with pre-installed screws, a snap-in housing, a snap-in blower and inside-out mounting duct connector for the fastest installation possible.
  • Installation Flexibility
  • The XB50's unique mounting frame can be expanded anywhere from 14" to 24" to fit any type of joist, I-joist or truss construction. Retrofit installations can be done entirely from the room-side without the need for access to the attic.
