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.
Direct-Drive Duct Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, these install inline in ductwork for use as an exhaust, supply, or booster fan. All fans 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.

Enclosure-Cooling Blowers
Create a more concentrated stream of air than enclosure-cooling fans to cool equipment faster. To save space inside enclosures, these blowers can mount outside. They draw cooler outside air into your enclosure or exhaust hot air through a louvered outlet vent. Incoming air is filtered to keep out dust and contaminants.
60 cfm blower has an open dripproof motor enclosure for relatively clean, dry, indoor locations.
Replacement filters are sold separately.
Surface-Drying Fans
Dry large flat surfaces such as floors with a concentrated stream of air.
Styles B and D have a low profile.
