Airfoils don’t change….That is unless you work with Envira-North Systems. Since 2003, we’ve continually searched, tested and modified airfoils to maximize their efficiency – solely for the purpose of moving large volumes of air a low speeds. Here’s what we’ve done:

  • Increased air speeds.
  • Reduced operating costs.
  • Decreased noise.
  • Streamlined appearance.
