Our fans utilize advanced aircraft technology to achieve superior performance.

The internal cowling, with its aerodynamic curves and tooling, provides the least amount of airflow resistance, maximizing air exchanges and reducing noise. Modeled after jet aircraft engine intake and exhaust systems, with specific curves on both the base and hood, you get a more efficient airflow and a whisper quiet operation. Constructed of aircraft grade spun aluminum, you won’t need to worry about rust or expansion issues in diverse weather.

Motor, Fan, Housing & Flashing System: All yellowblue fans come with high performance DC brushless motors designed to automatically adjust the fan speed to the amount of sunlight. The yellowblue motor is high-efficiency and maintenance free with a long service life (expected life span of 25 years). The fan blades are designed specifically for each system and pitched for maximum air flow to operate whisper quiet throughout the day.

The yellowblue fan housing and flashing are made from aircraft grade spun-formed aluminum for the utmost quality protection. The inner housing system is aerodynamically designed to produce the highest possible radial air exhaust. The outer shell is powder coated and aesthetically pleasing.
