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.
High-Output Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard blowers can handle. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, drying, ventilating, and exhausting. Blowers with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water. It is the responsibility of users in California to follow local energy efficiency regulations. Operating these blowers at a high airflow may violate these regulations.
