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 Hazardous Location Spark-Resistant Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard hazardous location spark-resistant blowers can handle. They have an explosion-proof motor that is UL listed for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G 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.

High-Output Spark-Resistant Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard spark-resistant blowers can handle. They have an aluminum housing for spark resistance. They 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. 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.
