Fan Grilles | McMaster-Carr

Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.

Shielded Equipment-Cooling Fan Guards

Mesh Guard for Square Fans

Mesh Guard for Round and Oblong Fans

Honeycomb Guard for Square Fans

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.

Mesh fan guards work for general purpose shielding.

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.

Equipment-Cooling Fan Kits with Thermostat

With the addition of a thermostat, the fans in these kits switch on only when needed. All kits include a fan, guard, and power cord. They keep heat-sensitive equipment such as electronic components cool.

Kits with a filter remove dust and other particles from the air. Replacement filters are sold separately.

EMI/RFI-Shielding Enclosure Vents

These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.

Screw through the vent frame to mount on the surface of your enclosure. A shielded foam gasket fills the gap between the enclosure and the vent.

Also known as attenuation, interference reduction at frequency measures how much interference is blocked. These vents have high attenuation and work for most applications.
