Altra-Air Sailfin HVLS Fans

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 at low speeds. Here’s what we’ve done:

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

Safety
Envira-North’s blade toppers prevent a rotor from failing in the unlikely event of a catastrophic failure of the hub or drive system. The collet-type friction drive bushing connecting the hub to the reducer shaft allows controlled slippage in the event of a seizure of the reducer mechanism, or a failure of the soft start feature in the control panel.

Warranty
Altra-Air fans come with a lifetime warranty on the blades and hub. The motor, gear reducer and VFD control panel come with a three year limited warranty.
