Revolution 4-Inch Variable Speed Blower

More volume. More control. More cooling. With a custom conformal-coated control board engineered specifically for its hand-built, soft-start brushless motor, it achieves performance levels once thought unattainable. User-adjustable speed settings allow operation from 30 CFM to an impressive 420 CFM, which is made possible through advanced development techniques and computer-controlled blade balancing. Designed specifically for motorsport racing, long carbon fiber-reinforced thermoplastics were chosen for their excellent rigidity, impact resistance, and lightweight properties. Like all Chillout products, the Revolution Series Blowers are backed by a one-year warranty against manufacturing defects and are engineered for long-term reliability. Variable speed: 30–420 CFM Power range: 0.2A to 12.5A 4-inch duct connection Rugged housing with vibration-resistant mount points Integrates with Chillout Systems air delivery setups Built for endurance. Tuned for performance.
