In Norway, a performance test was conducted with two LUF 60 units including Power Blower (PB 200).
The fire department filled the city rail tunnel between Kristianborg and Oasen with smoke, to test out the ventilation function on their brand new firefighting robots. Different ventilation practices were tested, such as suction (negative pressure), as well as positive pressure ventilation. Observations of turbulence and effects of equipment settings on best ventilation performance were documented by the technicians.
