About Sound Levels
To choose an alarm or speaker that’s loud enough, first determine the decibel (dB) rating of background noise.

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

Hazardous Location Equipment-Cooling Fans
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.

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.
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.

Hazardous Location Equipment-Cooling Fan Kits
Cool electronics and other sensitive equipment in potentially unsafe areas. These fans are non-sparking, so they’re safe for use around gas and explosive dust. They also withstand washdowns, occasional submersion in water, and wet weather. They’re not for use in mines. Ball bearings reduce the heat that’s generated to prolong fan lifespan.
