Has anyone seen or heard any info on HVLS fans in non-storage hazard applications?
We are seeing them frequently in fitness centers and apartment clubhouses, even in some larger loft apartments. It seems like the study that led to the guidelines in NFPA 13 11.1.7 (2016 ed) was based on storage applications. Does anyone know of any information or studies done in other hazard types? As far as I can tell, NFPA 13 does not differentiate between hazard types for the HVLS rules, but I was curious how they affect residential and light hazard systems, or if there is a minimum HVLS size or well defined criteria. Some of the new 'industrial look' residential fans have straight airfoil blades, but I don't know if they qualify. Any info would be appreciated! Thanks, Matt
