Our Air Circulater fan is an integral part of cooling, heat circulation air within any building or facility. This range of fan work in conjunction with, and are not a replacement for air conditioning, heating, and exhaust fans. Our fan comes with double ball bearing which are permanently lubricated for a longer life. The smoothly designed blades ensure higher air delivery and minimum noise level. With its unique signature grill and deep-pitched propeller, the 630 moves air up to 70 feet while aerodynamically circulating all the air in a room. The 3-speed control, located on the side of the air circulator's base, is easy to access and allows for speed selection to meet any circulation need.
