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.
Blowers with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.
Blowers with a multidirection mounting bracket can be rotated to discharge air in any direction.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
