16" circular oscillating pedestal fan. The Active Air Infinity fan is the perfect pedestal for simulating the natural patterns of wind. The circular oscillating motion provides air movement to more areas of the garden so more air is circulated throughout. This is especially ideal for those who use CO2 enrichment, as the downward air projection picks the extra CO2 up off the ground and distributes it back to the plant canopies. Built-in timer and adjustable 3-speed motor Adjustable height Circular oscillation Five foot cord
