5" 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.

Low-Voltage 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. All have UL recognized components.

Equipment-Cooling Fans

Also known as muffin fans, these keep heat-sensitive equipment such as electronic components cool. All have UL recognized components and are CSA certified. Fans with quick-disconnect (QD) terminals are compatible with quick-disconnect (QD) power cords.

Sleeve bearings are impact resistant, so they are ideal for applications involving movement and vibration.

Ball bearings reduce heat generated during operation, which extends the life of the fan.

Wet-Location Equipment-Cooling Fans

Able to withstand dust and water splashes, these fans are IP rated. Also known as muffin fans, they keep heat-sensitive equipment such as electronic components cool. All have ball bearings to lower the heat that is generated from the fans for a longer service life. They also have UL recognized components.

IP55-rated fans can also stand up to washdowns from low-pressure jets of water.

Install fans with wire leads directly to your power source—there’s no need for additional connectors.

Use fans with quick-disconnect terminals to quickly connect and disconnect wiring from the terminal. Optional quick-disconnect power cords allow you to add a NEMA plug to these fans, so you can connect them to a standard outlet.
