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.
Hanging Box Fans
Easily hang these fans from your ceiling using the attached bracket and a mounting chain kit (sold separately). They're more powerful than our standard box fans. Made with a heavy duty 12-gauge welded wire mesh guard, these fans will stand up to tough environments. Plastic guard clips help reduce vibration between the housing and the guard, making these fans quieter. They require little maintenance thanks to their totally enclosed, high-efficiency motor and sealed ball bearings.
Belt-drive fans are quieter and have a longer life span than direct-drive fans because their parts can be replaced if worn or damaged.

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 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.
