With the Broan-NuTone® speed control dial, you can turn any PSC bathroom fan into an adjustable speed fan. With the easy-turn dial, you can set your fan's speed and noise level to whatever is desired. By adjusting your fan's speed, the noise level, CFM and energy usage will change automatically, allowing you to adapt to all bathroom applications with a turn of the dial. Its bright, white color allows the Broan-NuTone® speed control dial to complement any bathroom setting or decor. Its sleek, modern design is the great addition to the complete fan offerings of either Broan or NuTone®.
