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 Upblast Roof-Mount Exhaust Fans
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

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.

Direct-Drive Corrosion-Resistant Duct Fans
A galvanized steel housing offers good corrosion resistance. All of these direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. The 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.

High-Flow Low-Pressure Compressed Air Blowers
Also known as regenerative blowers, use these to produce high-flow compressed air with low pressure or vacuum to operate pump drives, lift tables, and conveying systems. Compressed air blowers are also used for drying, exhausting, and aeration.
Air circulates inside the blower housing to compress air, which generates pressure or vacuum. Single-stage blowers circulate air once and then exhaust.
Inverter-rated blowers have a motor that can run at slow speeds without overheating, so they can be used with a motor speed control (variable frequency drive).

High-Volume Low-Heat Air Blowers
Combine high-volume airflow with low-heat output for warming and drying. These blowers tilt to direct airflow.
Blowers with removable mounting feet have two feet that you can detach and use as hooks for hanging.
Blowers with a fixed airflow rate are portable, so you can carry them from job to job.
