SBS Exhaust Ventilation Fan

Meet battery room ventilation safety requirements and create an automated hydrogen gas ventilation system using the SBS Exhaust Fan in conjunction with the SBS-H2 hydrogen gas detector. This 12″ x 12″ fan automatically vents out dangerous hydrogen gas that builds up in battery charging rooms/areas.

The flexible fan design, featuring a sliding collar, works on walls between 1.5″ and 8″ thick, allowing for easy installation. The fan is weather resistant due to fixed external louvers with motor-driven internal louvers.
