Schaefer’s Slant Wall Fans provide growers with efficient and low-maintenance cooling and airflow.

Schaefer tests every product in house — but also takes the extra step to ensure its products’ quality and efficiency by verifying its data through third-party testing. For example, the company’s Slant Wall Fans were sent to be tested at the University of Illinois Urbana-Champaign’s BESS Lab, whose results can be found at bess.illinois.edu. Brad Gaddy, sales manager at Schaefer, outlines additional benefits to choosing Slant Wall Fans.

Five-blades - Slant Wall Fans are available in 24- to 54-inch sizes in either three-blade or five-blade options. The advantage of utilizing five-blade fans in your facility, says Gaddy, is a significant reduction of noise. With five-blade fans, “There’s less space between the blades,” he says. “So therefore, you don’t have as much noise from the chopping of the air.”

Belt drive - The belt drive element of the Slant Wall Fans puts less stress on the fan motor. “When you put a big fan blade attached to a motor [in a direct drive fan], the motor has to work harder to spin the blade than it does with a belt and pulley system, which lessens the work the motor has to do,” Gaddy says. “It does benefit [if you have bigger fan blades] to have a belt drive versus a direct drive.”

Resistant to the elements - The Slant Wall Fan’s slanted shape also increases its longevity. “Water or snow can run off the top of the housing and not get into the housing,” Gaddys says. “It’s an added element of weather proofing.”

Thermally protected motor - Temperature sensors in the windings (the metal that creates an electromagnetic field to spin the motor) protect against overheating of the fans. After reaching a certain temperature, the fan will automatically stop running to prevent damage to the motor, Gaddy says.
