The emission of aerosols from the manhole can, for example, be prevented by using the blower device "Aerokill". Driven by the vehicle hydraulics, this device generates a strong air-flow above the manhole opening which forces the aerosol and water mist to collide with the inner wall of the manhole.

This reaction causes the aerosols and the water mist to disperse and drain back into the sewer. Due to its high air conveying performance, the system is also suitable for the ventilation of sewers [SteinD00a].
