Custom SPAL Brushless Fan Kits

SPAL Brushless Fan Kits

Pa = Pressure / (1Pa) = (# x .004) / Resistance of Air Flow 
CFM = (# x .59)

SPAL charts can be a little confusing at times. This is to help you understand the advantages of a Brushless Fan over a Brushed Fan.

Brushless Fans have two major advantages:
   1:  they can handle more amperage which gives them increased power and torque
      2:   being brushless there is no arking of electricity which gives them longer life (up to 4-5 times the life of a Brushed fan.

If you have a thick radiator with a heavy fin count (anything over 2.25 inches thick with 14 or more fins per inch), you will want to look at this chart to help you make the right product choice for your application. SPAL Brushless Fans are able to overcome the static resistance pressures that you will encounter with thicker radiator cores and provide you with adequate airflow to keep your radiator operating cool!
