The purpose of the air extraction system is to expel variable quantities of air from the boat’s internal areas (toilets, laundry room, kitchen, systems areas/plant rooms etc.) to ensure (working in synergy with the air handling unit) the air is completely changed the stipulated number of times per hour in line with the technical specification.

The extraction systems are typically dimensioned to function continuously, with the possibility to decrease the flow of air/noise during its overnight operation by using the appropriate switch to modify the speed setting.
