These excellent quality wall mount fans feature 3 speeds with a speed control knob and cord. The fans have a powder coated steel grill and a chemical resistant polypropylene blade. They can oscillate 90 degrees or can be locked in a non-oscillating position. The fan head can also be tilted up and down for more directional control. Both are very quiet and efficient. Ideal for home, greenhouses, garages, workshops and other areas with limited floor space.
