Fans get dirty... plain and simple! Rarely are our products placed in spotless environments, and although they're built with durability and rugged conditions in mind, cleaning fans regularly can extend their lifetime, cut down on replacement costs, and even save you money on energy consumption. That's why it's important to keep them as free from dust and dirt buildup as possible

Over time, dirt will accumulate on two major areas: the guard behind the motor and the fan blade itself. If left untreated, this can lead to a number of issues. First, a fan guard caked with dirt will not allow proper airflow over the motor, causing it to heat up as well as increase its amp draw. Higher amp draws mean greater energy consumption, which in turn leads to higher electric bills… And no sane person wants that.

Dirt on the fan blade can be equally as troubling. Since the motor and blade are designed to function as one unit, any sort of buildup can cause an imbalance in the blade’s rotation. This can place constant stress on the rotor (due to fan blade “wobble”), and in some cases cause a fatigue crack on a blade paddle.

Want to avoid these mishaps? Follow these three quick steps below!

  1. ​​​​​​​​​​​​​​Remove fan guard.
  2. Wipe fan of all dirt, dust, and grease.
  3. Replace guard and enjoy!
