SystemAir Revolution Silenced AC Fan
The SystemAir Revolution Silenced AC Fan has set the industry standard for inline fans. This unit moves huge volumes of air in silence. The carefully-engineered casing and acoustic foam reduce the noise of a standard unit without affecting air flow.
The Revolution Stratos AC version offers greater air flow and performance under pressure than any other AC fan on the market, without all the noise. The Stratos can be controlled by Triac, step transformers or frequency controllers.
