Vent Power-12/24 or 48 Volt
Cat. No. Power Vent
$94.00

Lead-acid batteries produce hydrogen gas when charging. But if the battery box is left open to vent gas in cold climates, the batteries get too cold and battery capacity is significantly reduced.  A v e n t that solves this problem is especially important when battery boxes are placed in basements, garages and sheds.  When heat rises in the structure, a low pressure area forms around the box, cool air flows into the box and gasses vent into the structure.  The Power Vent controls battery box venting, removing hydrogen gas while reducing  cold air infiltration into the box.  The Power Vent contains a gravity-operated damper that normally stays closed.  Designed for battery banks under 2200 Ah and charge rates under 125 amps.  Fan can be operated from the auxiliary relay on aXantrex XW inverter, from the auxiliary relay on a OutBack FX inverter (use 12 volt-fan for all OutBack inverter voltage) or by a voltage controlled switch (sold seperately). When connected to a voltage controlled relay the fan operates only when the batteries are being charged and blows gas vapors out 

The 12/24 volt unit uses 3 watts and pushes air at 6 CFM with a 360 ° maximum change of direction.
