Manufacturing Runs The World

They didn’t just build fans — they invented an industry


Listen Later

When cows were overheating in the California sun, Jaylin Krell’s father and grandfather set out to solve a problem no one else was paying attention to. That’s how MacroAir created the first-ever HVLS fan — a category that changed the way we cool large spaces forever.

In this episode, Jaylin shares how they turned that breakthrough into a global business, why they’ve resisted the pressure to “scale big,” and how small, family-run manufacturing still wins by staying human-first.

Whether you're a business owner, engineer, or just curious how innovation actually happens — this story will change the way you see manufacturing.


You’ll hear:

  • The untold origin of HVLS fans (yes, it started with cows)

  • Why staying small was a strategic advantage
  • How MacroAir balances innovation with a human-first manufacturing culture
  • Real tactical lessons for any manufacturer trying to scale smart
    • What’s next for the future of airflow, noise reduction, and IoT-enabled fans
