PPVs included in UL study; Participating manufacturers included Ventry, Unifire, Ramfan, Tempest, SuperVac and Leader.

See also photos of PPV Fan Flow Tests, Dec 2014. Many manufacturers participated and all fans shipped to UL were tested.

These photos were taken by James Neils during Live Fire Tests in January 2015, part of the huge study by Underwriters Laboratories Firefighter Safety Research Institute (UL FSRI) on PPV effectiveness. James traveled to Chicago three times, serving on the panel of PPV fan manufacturers.

Please note: only a few of the photos James took are shown here. To view and flip through the photos more easily and see all of them, please visit our UL Vent Study Live Fire Testing album on Facebook. No account or identification is necessary.
