Tests are part of larger UL FSRI PPV study

James Neils took these pics of initial PPV Fan Flow tests while in Chicago as a panel member. James also attended live fire testing in January 2015.

Ventry Solutions, Inc. was among several PPV fan manufacturers who participated in the multi-year study on the effectiveness of positive pressure ventilation (PPV) and attack (PPA), incorporating modern construction practices, in the context of the Fire Service and fire fighting, by Underwriter Laboratories Firefighter Safety Research Institute (UL FSRI). In summary, UL studied the use of PPV and PPA in modern construction single-family dwellings.

Given his identities as a volunteer fire fighter, mechanical engineer, pilot, and CEO, plus his great fondness for all things science, James Neils was the quintessential kid in a candy store. He traveled three times to the UL FSRI’s facility in Chicago, Illinois. As a member of the panel, his ideas and experience were incorporated into the experiments and he got to observe actual testing on two occasions.

Please note: Only a few of the photos James took are shown here (where they are not easy to view) so please, see our UL Vent Study Fan Flow Testing Facebook album for all photos of this event, where you can flip through them easily and see larger images. No account or identification is necessary.

The test facility was impressive in scale!

A huge, impressive facility!

James and Great Aunt Ruth

And last but not least, James got to visit our Great Aunt Ruth while in Chicago.

The FSRI is to be commended for their objective, comprehensive, and transparent approach to this study.

The results of the ventilation study are expected in this first half of 2016. These are photos taken by James during his visits to the facility during which he observed ppv fan flow testing and live fire tests. (URL: Last accessed 2016-02-16)
