Several years of research have gone into determining the best combination of materials to produce a lightweight yet powerful wall fan that we call the LB645.
The fan's speed and blade swing are regulated by two strings; pulling one will increase speed while pulling on the other changes the swing direction of the blades. This special design is included to afford you the ease of operating this fan even if you install it on lofty heights.
It's extra silent and delivers cool breeze year round.
