Altra-Air Sailfin Fan is Now Gearless!
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 Advantage
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.
Sailfin represents everything users want in an HVLS Fan, it looks nice, moves a ton of air and consumes very little energy!
Altra-Air fans come with a lifetime warranty on the blades and hub. The motor and VFD control panel come with a three year limited warranty.
Envira-North’s blade toppers prevent a rotor from failing in the unlikely event of a catastrophic failure of the hub or drive system.
