FAN GUARDS

 

FAN GUARDS

Function : Protect fingers, cables, and debris from coming into contact with moving fan blades.

Shielded Equipment-Cooling Fan Guards

Made of conductive metal, these guards cover fans to block EMI (electromagnetic interference) and RFI (radio frequency interference). The screen also helps keep large debris out of your enclosure and protects fingers from spinning fans.

For Square Fans

Mesh

Mesh—Mesh fan guards work for general purpose shielding.

Honeycomb—Honeycomb fan guards shield sensitive parts, such as precision measuring equipment. They have high interference reduction at frequency, also known as attenuation, so they block most interference. The beryllium copper gasket seals gaps between the fan guard and your enclosure for additional protection. Do not use in direct contact with acetylene.
