| How it works |
| |
 |
| |
| Positive pressure ventilation – the
safe and quick method for ventilation in the case of heat, gas, dust
and smoke |
| |
|
High pressure fans serve the quick, forced ventilation of
rooms in residential buildings, halls, multi-storey car parks,
etc in the case of smoke, gas and heat caused by fires.
During positive pressure ventilation, high-performance fans
are positioned outside the building and a stream of fresh air
is applied. The conical air flow is compressed at the entrance
to the building, thus excluding the possibility of air back-flow.
The light initial positive pressure sets the air masses in the
building in motion in the direction of an existing opening,
such as a window or smoke flap etc., or one that is subsequently
created. The resulting air flow then transports smoke, heat
and poisonous gases out into the ambient air without major turbulence. |
| Positive pressure ventilation works independently
of the size of the building. The effect can be increased by
the use of several fans, as shown here in the case of a fire
in a multistorey building. In addition, adjacent areas can be
kept free of smoke and gas. |

| |
| The advantages of positive pressure ventilation
during operations are |
|
| |
|
- Crew quickly has improved visibility
- Crew can work with fresh air at its back
- There is a remarkable drop in ambient temperatures
- The air flow deals with the water vapour from extinguishing
- Smoke is removed evenly from the floor, ceiling and corner areas
- The air flow can be controlled
