Positive Pressure Ventilation Study will Help Firefighters World-Wide
Greatly improving the fire service’s understanding of positive pressure ventilation and attack and furthering its safe and effective use, UL Firefighter Safety Research Institute (FSRI) has released the results of their huge, multi-year study.
Fire dynamics has changed dramatically during the three decades we have been manufacturing Ventry® PPV Fans. Tactics must also evolve! This study is a huge step in the right direction. The materials created from it are credible, science-based, and brand-neutral; we believe these can improve ventilation safety and efficacy in the fire service world wide:
- Online PPA/PPV training course - Complete training is 2 hours; the abbreviated course is 1 hour. Choose the course that works for you.

Also, an exceptional summary of the study’s findings titled, “PPA Deconstructed - UL FSRI experiments reveal the value of ventilation” by panelist Nick Ledin, is available online from FireRescue Magazine.
VSI’s Participation in the PPV Study
Having manufactured PPV fans since the late 1980s and always striving to make exceptional tools that save lives, we are grateful for this study. We will work to share other aspects of this important work and are studying the material and training carefully.
Anecdote. Ventry Solutions, Inc. provided several Ventry® Positive Pressure Fans for the UL study, one of which delayed an experiment when it rolled the carpet up in the living room of the structure!
For the study itself, the Technical Panel chose wisely to use an “average” fan [2 p17] [4 p70]. Though disappointed that our brand would not appear in all the photos, we are proud that ours is definitely NOT an average fan! A Ventry Fan is shown in the online training course, however, to demonstrate fan tilt and placement (see the screen shot above) [1a].

Brush Burning Fans
Contractors often want 4 or more fans for huge land clearing projects; they soon realize only one Ventry Fan is needed! Several of the unique qualities which make our fans ideal for fire fighting also make them a great investment for brush burning.
