The Comfort Air Gold circulation fan is equipped with a variable speed control that allows for comfort at several different settings, guaranteeing your satisfaction at any level of air flow. The exhaust feature pulls the stale air and unwanted odors from your coach, which then forces new air in from an open window. If you want a gentle breeze to cool you from overhead, simply close the dome and the air driven from the exhaust mode will bounce off the dome and back into the coach, creating the effect of a ceiling fan. For a more dramatic flow of air into your coach, switch the fan to intake mode where the variable speed gives you the power to set the fan at any speed up to 950 CFM, the most on the market.
