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.

Desk Fans

Non-Oscillating

The fan head tilts to direct air where it's needed.

Portable Blowers

Powerful enough for use with flexible duct, yet light enough to carry from job to job. Use these blowers for equipment cooling, material conveying, drying, ventilating, and exhausting. Blowers have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

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).
