Positive pressure ventilation ppv is a ventilation technique used by the fire service to remove smoke heat and other combustion products from a structure.

Positive pressure ventilation fans fire service.

Designed for high powered air movement the super vac positive pressure ventilators are for use in extreme conditions. As the fire service awaits new ppv research homer robertson reviews ppv basics. Ppv fans come in many different sizes from 16 blades that fit in the tightest of apparatus compartments to large scale ppvs for the largest of jobs. The changing dynamics of residential fires as a result of the changes in home construction materials contents size and geometry over the past 30 years compounds our lack of understanding of the effects of ventilation on fire behavior.

This allows firefighters to perform. Positive pressure ventilation is one of the primary methods utilized by the fire service today. Positive pressure ventilation uses positive airflow to remove heat and products of combustion from a structure on a fire scene. When utilized appropriately it is a great problem solver.

The aim of this national institute of standards and technology video is to improve firefighter safety by enabling better understanding of structural ventilat. We have a solution for any ventilation challenge out there with negative and positive pressure fans rescue saws confined space large scale fans smoke controlling devices and smoke training aids. The objective of this research is to improve firefighter safety by enabling a better understanding of structural ventilation techniques including positive pressure ventilation ppv and natural ventilation and to provide a technical basis for improved training in the effects of ventilation on fire behavior by examining structural fire ventilation using full.
