BROAN ULTRA GREEN™ Series Fans deliver everything you wished for in a bath fan – premium ventilation to help reduce airborne pollutants, extremely quiet operation, energy efficiency, consistent power and most impressively, the fastest, easiest, most universal installation available. These fans are ideal for both spot ventilation in humid bathrooms, as well as continuous ventilation to meet various building codes and Green Building standards around the United States.

Features:

• 50 CFM reduces humidity to quickly eliminate fogged mirrors and manage moisture in bathrooms up to 45 square feet, so your vision will always be clear and your surroundings will always be comfortable
• ULTRASilent™ with QStream™ Sound Technology results in operation at less than 0.3 Sones – the quietest sound rating attainable -- for an environment that is so quiet, you’ll likely forget the fan is on
• ULTRAQuick™ Installation Technology uses an exclusive telescoping mounting frame with pre-installed screws, snap-in housing, snap-in blower and an inside-out mounting duct connector that are the fastest, easiest, most universal installation
• Retrofit installations can be done entirely from the room-side – no attic access required. This means a faster, easier installation, so you can move on to something else
• Unique telescoping mounting frame can be placed and fastened through drywall hole because it expands from 14” to 24” and fits any type of joist, I-Joist or truss construction for a “no guesswork” installation to make the work fast and easy
• Snap-in housing and blower further simplify installation since you can hear – and feel – when they are properly seated. Easy-to-position carriage allows housing location adjustment between joists so you can control the correct ceiling placement
• ULTRASmart™ DC Motor & Control Technology provides energy efficiency almost 10 times greater than ENERGY STAR® requirements and maintains rated power (CFM) in nearly every installation. You have confidence you’re getting the expected performance and won’t even notice the fan usage on your utility bill
• UL Listed for use over tubs and showers with a GFCI circuit; so you can capture the steam before it spreads throughout the room by locating your fan exactly where you need it the most
• Compatible with Radiation Damper RDFU which helps prevent flame and heat from spreading to other areas in multi-level buildings
• Can be used to comply with ASHRAE 62.2 and CALGreen
