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.
Hazardous Location Spark-Resistant Blowers
These blowers have an explosion-proof motor that is UL listed for hazardous locations. They also have an aluminum housing for spark resistance. These blowers install in ductwork similar to duct fans, but are for use where high static pressures are present. 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. 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.

Spark-Resistant Blowers
These blowers have an aluminum housing for spark resistance. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting. All blowers have a totally enclosed motor enclosure, which 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.
