HOT ! BROAN-NuTone PTE511RK Fan

The BROAN-NuTone PTE511RK is a high-performance selectable CFM bathroom exhaust fan designed for versatile installation in professional HVACR applications. As a direct XB110 replacement, as well as a drop-in substitute for XB80 and ZB80 models, it simplifies inventory and retrofitting for contractors. This unit utilizes DC motor technology to maintain constant CFM performance against varying static pressure, ensuring optimal ventilation regardless of ducting complexity. The integrated humidity sensor or wall-switch control allows for 50, 80, or 110 CFM settings, providing precise IAQ (Indoor Air Quality) management. Built with a low-profile housing, it fits 2x8 ceiling joists and features a 6-inch duct connector for reduced turbulence and whisper-quiet operation. For technicians troubleshooting airflow efficiency, the PTE511RK offers a reliable solution with Energy Star certified efficiency and rugged construction suitable for continuous run environments.

• 
  Multi-speed flexibility allows technicians to toggle between 50, 80, and 110 CFM to meet specific zone requirements.


• 
  Brushless DC motor ensures whisper-quiet ventilation and significant energy savings over traditional PSC motors.


• 
  Retrofit-ready design allows for room-side installation without requiring attic access, reducing billable labor hours.


• 
  Pick-A-CFM technology eliminates the need to carry multiple fan SKUs on the service truck.


• Compatible with 6-inch ducting to maximize airflow velocity and minimize static pressure buildup.

Is the PTE511RK a direct fit for older XB and ZB series housings?
Yes, this model is the specific engineering replacement for XB110, XB80, and ZB80 units, utilizing the same footprint for seamless swaps.

Does this fan handle high static pressure in long duct runs?
The DC motor technology automatically adjusts torque to maintain the selected CFM levels, even when encountering resistance from flexible ducting or long runs.

Can this unit be used for continuous ventilation?
The PTE511RK is rated for continuous operation, making it ideal for meeting ASHRAE 62.2 mechanical ventilation requirements in residential builds.
