150mm wire fan guards protect cabinet cooling fans while maintaining quiet fan operation and maximum airflow. 150mm cooling fans are popular on large electronics and cabinet cooling setups. Wire form finger guards protect cooling fans without blocking airflow like mesh fan guards. While mesh and perforated metal fan guards block up to 50% of the fan’s air output, wire fan guards block a miniscule 5%. Unobstructed fans cool faster and run slower, reducing heat buildup and unnecessary noise. GardTec wire fan guards are your solution for electronics cabinet cooling.
