How does a boat air conditioner system work?

Air moves through the ducts as the boat is in motion. Each duct is also fitted with a cowl, or a hood-shaped covering, to help increase airflow. In a powered ventilation system, one or more powered blowers does the work of circulating air through the ducts.

Why do you need a bilge blower on a boat?

Bilge Blowers are the most important ventilation system source for boats with gasoline engine spaces or rooms. They should also be used in diesel engine rooms or spaces. Dangerous fumes can accumulate in the bilge, creating a situation ripe for a fire or explosion.
