2.36" Fans | 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.

DC Equipment-Cooling Fans

Running on 48V DC power or lower, these compact fans fit inside electronics and other small, heat-sensitive equipment to keep things cool. They're also known as muffin fans. Some meet American and Canadian safety standards.

Fans with ball bearings generate less heat as they run, so they have a longer life than fans with sleeve bearings.

Fans with sleeve bearings are good for less demanding applications, such as cooling prototypes or parts that aren’t used often.

High-Output Equipment-Cooling Fans

These fans produce greater airflow than standard equipment-cooling fans. Also known as muffin fans and electrically commutated (EC) fans, they keep heat-sensitive equipment such as electronic components cool. Ball bearings keep them running smoothly and quietly, reducing friction to increase their lifespan. All have UL recognized components and some are CSA certified.

Hazardous Location Equipment-Cooling Fans

Square

Safely cool electronics and equipment where explosive gases could be present due to equipment failure. ATEX certified, these fans meet European standards for hazardous locations. They’re also IP rated, so they seal out dust and are protected from water if briefly submersed. All have ball bearings that decrease noise for quiet operation. Their bearings reduce heat as they run as well, extending their life.
