Axial and centrifugal jet fans are used in parking garages for daily supply and extract ventilation and they ensure smoke extraction to support the fire service in case of fire. They have an impulse effect on the air due to the generated air jet. Thus, there is a movement of air in the respective air flow direction towards the central extract air fan or towards the next jet fan unit.
