QuietCool 50 Watt Solar Smart Roof Mount Attic Fan with Smart App Control for 24/7 Runtime

The QuietCool AFR SLR SMT-50W Solar Smart Roof Mount Attic Fan is engineered for homeowners who want powerful attic ventilation, premium durability, and maximum energy efficiency—all in a clean, roof-mounted design. By combining solar power with intelligent smart controls, this system delivers consistent, optimized airflow while reducing reliance on traditional energy sources.

Powered by a 50-watt monocrystalline solar panel, the AFR SLR SMT-50W uses renewable energy to ventilate your attic during the day, while automatically supplementing with AC power when needed. This hybrid operation ensures reliable performance around the clock, helping to reduce extreme attic heat buildup that can drive up indoor temperatures and strain your HVAC system.

With airflow performance up to 1,119 CFM on high and 686 CFM on low, this fan effectively removes heat and moisture from the attic, helping to protect your roof structure, improve overall home comfort, and lower cooling costs.

The integrated QuietCool Smart App Control gives you full command of your attic environment. Featuring a built-in thermostat and humidistat, the system allows you to monitor and adjust conditions directly from your smartphone. Smart Mode automatically adjusts fan speed based on real-time attic temperature and humidity, maintaining optimal ventilation without constant manual input.

Built for long-term durability, the AFR series features a one-piece stamped steel hood and a perforated cylindrical housing with an integrated wildlife guard. This design enhances airflow while preventing unwanted intrusion from pests. A high-quality UV-resistant paint coating protects against fading, chalking, and harsh environmental conditions, ensuring the unit maintains its performance and appearance over time.

Safety remains a priority, with a built-in fire safety shut-off that helps prevent the spread of flames in the event of extreme attic temperatures. The ultra-efficient DC motor delivers strong airflow with minimal energy consumption, maximizing performance while keeping operating costs low.

Designed for installation flexibility, the AFR SLR SMT-50W supports interchangeable flashings for compatibility with a wide range of roof types, including shingle, tile, and flat or low-pitch roofs (flashings sold separately). Installation is streamlined with built-in mounting features and a 20-foot AC/DC power adapter for convenient setup.

The QuietCool AFR SLR SMT-50W Solar Smart Roof Mount Attic Fan delivers a refined balance of intelligent control, solar-powered efficiency, and rugged construction—providing a long-term solution for maintaining a cooler, healthier, and more energy-efficient home.
