Gearless Altra-Air Sailfin HVLS Fan

Altra-Air Sailfin HVLS fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, this large ceiling fan can create an evaporative cooling effect of 3 to 4 degrees Celsius throughout the facility.

The Sailfin Blade Design is a massive evolutionary step toward our most advanced airfoil, capable of producing a 6mph breeze.

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 to move large volumes of air at low speeds. Here’s what we’ve done:

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

Sailfin represents everything users want in an HVLS Fan, it looks nice, moves a ton of air and consumes very little energy!
