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 Blowers
Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard blowers can handle. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, drying, ventilating, and exhausting. Blowers that weigh 280 lbs. or less can also be used for material conveying. Blowers with an open dripproof motor enclosure are for relatively clean, dry, indoor locations. Blowers with a totally enclosed motor enclosure 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. 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.

Corrosion-Resistant Blowers
A 304 stainless steel housing offers good corrosion 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. 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.

Thermoelectric Coolers for Enclosures
Also known as Peltier coolers, these coolers use electrical current to transfer heat away from your enclosure while sealing out contaminants. They cool the enclosure to below the ambient temperature. The solid-state thermoelectric components require no maintenance and take up less space than an air conditioner or heat exchanger.
Rated IP66 and NEMA 4X, these coolers withstand weather, washdowns, and corrosive environments. They meet American and European safety standards.
Coolers without a thermostat run continuously when powered. Add a thermostat, timer, or switch to turn them on and off.
An optional extension bracket holds the cooler away from the enclosure wall for more space inside the enclosure.
Add a drain kit to remove moisture when condensation is likely, such as in humid environments and enclosures exposed to rapid temperature changes. The included hose directs water away from electrical components.
