Envira-north en680x7464 altra-air sailfin 20′ variable speed fan w/control & 2′ mount 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 5 to 8 degrees fahrenheit throughout the facility. The sailfin blade design is a massive evolutionary step towards our most advanced airfoil yet capable of producing a 6mph breeze. 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!! 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.
