Positive Pressure Ventilation (PPV) Fan

Introducing a substantial amount of fresh air into fire-impacted areas raises internal pressure to manage smoke dispersion.

It delivers instant benefits: enhanced visibility, lowered temperature and toxicity, regulated smoke flow, and minimized thermal radiation, which are advantageous for both firefighters and trapped people.

Firefighters need to choose the most appropriate fan for a given situation according to the layout of the ventilation site.

Positive Pressure Ventilation Attack Tactics

This tactic entails direct ventilation and smoke extraction in conjunction with firefighting resources to suppress fires. Its objective is to modify fire dynamics and swiftly diminish its intensity.
