PPV & Impulse Ventilation Testing

When water-based artificial smoke is introduced into a rapidly moving air stream, the particles that make up the artificial smoke evaporate much more quickly than they do in a static environment.

So if you are looking to produce an artificial smoke that better represents the smoke created by a real fire, we would always recommend the ViCount smoke generator, the smoke from which is virtually unaffected by fast moving air streams. Used world wide PPV training centre’s and to test impulse ventilation systems.

A Home Office report into PPV (Positive Pressure Ventilation) by the Head of the Fire Experimental Unit, Fire Research & Development concluded that the concept behind the technique of PPV was relatively easy to understand and the equipment simple to operate, but stressed the need for extensive training.

Our clients say…

We use smoke generators for fire simulations and positive pressure ventilation training for approx 10 hours per week. The smoke adds realistic conditions for Fire Fighters to train in but with safety in mind. Compared to our other generators, the Spirit 900 has much lower running costs.
