About Sound Levels
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 Blowers
Operate these blowers with a DC power source, such as your vehicle battery. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

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.

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.
