Bathroom exhaust fans are essential for maintaining indoor air quality, reducing humidity, and preventing mold and mildew. Among the most popular models in the U.S. market are the Broan 80 CFM bathroom exhaust fans with integrated lighting. These units combine ventilation with illumination, offering convenience and energy efficiency. This article provides a detailed overview of key models, their specifications, installation procedures, and features relevant to U.S. consumers, DIY enthusiasts, and professionals.
Overview of Broan 80 CFM Fans with Light
Broan offers several variants of 80 CFM bathroom exhaust fans with LED lighting, including models from the Flex Series, Ultra Green™, and Roomside Series. These fans are designed for rooms up to 75 square feet and are Energy Star certified for energy efficiency. They are also UL listed for use over bathtubs and showers when connected to a GFCI-protected circuit.
A common feature across these models is the integration of LED lighting, which provides energy-efficient illumination. Some models include humidity sensors that activate the fan automatically based on moisture levels, enhancing convenience and effectiveness.
Installation Procedures
Installation of Broan 80 CFM bathroom exhaust fans with light requires careful planning and adherence to manufacturer guidelines. The following steps summarize the general procedure, which may vary slightly depending on the specific model.
Pre-Installation Considerations
- Electrical Requirements: All models operate on a standard 110–120V power supply and require a dedicated GFCI-protected circuit for use over bathtubs and showers.
- Ventilation Requirements: Ensure the bathroom is properly ventilated, and the fan is connected to an exterior vent duct. Duct size is typically 4 inches in diameter.
- Tools and Materials: Prepare a screwdriver, drill, measuring tape, and installation hardware included in the package.
Step-by-Step Installation
- Turn off the power supply to the bathroom at the circuit breaker to ensure safety during installation.
- Remove the existing fan and ductwork (if applicable). Clean the mounting area and inspect for damage or obstructions.
- Install the mounting frame according to the manufacturer’s instructions. Some models use a telescoping mounting frame for easier installation.
- Secure the fan housing to the mounting frame using the provided screws. Ensure the fan is level and properly aligned.
- Connect the ductwork using the 4-inch polymeric duct connector. Ensure the duct runs directly to the exterior to avoid backdrafts and improve airflow.
- Wire the electrical connections according to the wiring diagram included in the installation manual. This typically involves connecting the fan and light to the power supply and control switches.
- Install the front cover and any additional components such as humidity sensors or light controls.
- Restore power and test the fan and lighting to ensure proper operation.
Broan emphasizes ease of installation with features like SnapFit Flange Kits, EZDuct™ connectors, and FoldAway™ mounting ears, which accommodate retrofit installations and spaces without attic access.
