Powered by just a slight breeze, the Vent-O-Mate ventilator automatically exhausts stale, hot and moisture-laden air from inside a closed boat to help eliminate mildew and keep odors from accumulating. There is no need to wonder why your solar powered vent is not working. Wind moving over the open grill on top creates a partial vacuum that literally sucks air out of the boat.
Nominal 4" vent size
Removes 350 ft of air per hour with a breeze of only 6 mph
Can theoretically cycle the air in a 30 ft sailboat in about 2 hours, under ideal conditions
