The Patterson DB Fan features an evenly distributed column of air and requires minimum space. The low-profile unit is a high-velocity, quiet fan with low noise emitted at just 60 decibels. Ease of communication is greatly improved with this level of noise reduction. The DB’s small footprint provides more headroom, allowing 50 percent more clearance than a similar performing 18" high-velocity fan, the company says. It also features a half horsepower motor to power the double blower, throwing an evenly distributed dual column of air 50' with minimal energy consumption.
