The Stealth in-line fan model features a durable yet slim form and spacious housing to minimize reverberation inside a narrow air chamber. Larger 10” and 12” models were manufactured with extra space ratios in their housing unit to accommodate a wide wind tunnel. The sound muffling Stealth design dampens residual humming from an accelerated wind torque and high-velocity vortex generated by rotational motion.
Coupling your Stealth in-line fan with the SpeedMaster Fan Speed Controller will not only endorse energy efficiency but also further contribute to sound dampening. A lower, equally efficient speed will be less noisy. The SpeedMaster solid state speed controller will allow gardeners to dial their fan speed to their precise CFM requirements and plant transpiration metrics. This device complements the Stealth motor by keeping it from running at maximum rpm by default. Insulated, ridged ducting will also further dampen any leftover minor sound.
