Make sure that you're purchasing an air circulator that provides you with the most effective & efficient air flow. The dynamic five-wing propeller blade moves 20% more air than a 12" oscillating fan. In order to obtain the best & most accurate air flow, the air circulator is fitted with an adjustable head (moves to a straight-up position), a rotary dial that offers three speeds (high, medium & low), a security lock to make sure the air circulator stays blowing in the correct direction & a pivoting design that can move to any desired air stream in a 90 ° arc (vertical to horizontal). For durability, the air circulator is made from high-impact, rustproof plastic & is equipped with a permanently lubricated motor. Fan Head Size: 8"; Fan Type: Base; Width: 10 1/4".
