The Power Vent - battery box ventilator

The Power Vent provides positive venting of a battery box. The built in back draft damper stops cold outside air from entering the battery box. The Power Vent can be easily installed in a battery box vent system using 2 inch PVC pipe. Many inverters and charge controllers have a 12 volt powered relay that can power the Power Vent. Power consumption is 3 watts. Air volume movement is 4 to 6 cfm. 24 and 48 volt fans are also available. Fan is replaceable.
