A fire in large objects can quickly become a disaster. For the fire department, it is hardly possible to orient in the smoky areas and the heat accumulation leads to an enormously fast fire spread. Mobile Grand Ventilators realise immediately better visibility and lower temperatures in burning buildings. Rescue operations can be handled faster, safer and more efficient.

While in theory a couple portable positive pressure fans equals a greater cumulative air output number than a Mobile Grand Ventilator, this does not mean these units will be able to ventilate a large scale structure in case of a fire. Large structure ventilation requires overcoming incredibly resilient back pressures, something only a MGV® can achieve.
