New low-noise fans are oil-free to prevent contamination risks

The new Direct Drive high-volume, low-speed (HVLS) fan (photo) produces no noise and uses no oil. The lack of gears reduces noise, while the absence of oil means the Direct Drive HVLS fan eliminates any opportunity for contamination. The fan comes standard with 24-ft dia. blades, but 20-, 16-, 12- and 8-ft dia. options are also available. A single Direct Drive HVLS fan can circulate a large volume of air up to 85 ft from the fan’s center in all directions for optimal heating or cooling of an area encompassing up to 22,000 ft 2. The unique design of the fan directs air outward from the center in a conical shape, eliminating dead-air holes directly beneath the fan and in corners, translating to more uniform airflow from floor to ceiling and from wall to wall. Without a gear motor, the Direct Drive HVLS fan can be installed in roughly half the time it takes to install a traditional HVLS gear-motored fan, says the company. — Rite-Hite Corp., Milwaukee, Wis.
