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.
Low-Noise Enclosure-Cooling Vortex Tubes with Thermostats
Often used in low-noise environments such as labs and clean rooms, these are quieter than standard enclosure-cooling vortex tubes. Set the thermostat and the tubes switch on only when needed. They convert compressed air into a stream of cold air to keep electronics within enclosures from overheating while also keeping dust and other contaminants out. These vortex tubes chill compressed air by 50° F or more. They include a ducting kit to distribute cool air throughout the enclosure. All are rated NEMA 12 to resist dirt, light water splashes, and oil/coolant dripping.
Vortex tubes with dual air outlets have a higher cooling capacity than other vortex tubes. Use them to cool large enclosures and electronics that generate significant heat. Direct the two air streams independently for targeted cooling. With two air mufflers and two ducting lines, these vortex tubes take up slightly more space in your enclosure than vortex tubes with one air outlet.
Replacement filters are sold separately.

Low-Noise Washdown Enclosure-Cooling Vortex Tubes with Thermostats
In addition to being quieter than standard enclosure-cooling vortex tubes, these stand up to washdowns and weather. They convert compressed air into a stream of cold air to keep electronics within enclosures from overheating while also keeping dust and other contaminants out. Set the thermostat and the tubes switch on only when needed. All include a ducting kit to distribute cool air throughout the enclosure and air mufflers to reduce noise. They also have an inline compressed air filter, which prevents moisture from building up inside the enclosure to further safeguard electronics.
Vortex tubes with dual air outlets have a higher cooling capacity than other vortex tubes. Use them to cool large enclosures and electronics that generate a lot of heat. Direct the two air streams independently for targeted cooling. With two air mufflers and two ducting lines, these vortex tubes take up more space than vortex tubes with one air outlet.
Vortex tubes with an electric thermostat require a 120V AC outlet. Those with an internal outlet are best for areas where external outlets are not available or where it would be unsafe to have an external electrical connection. Choose those with an external outlet if you need separate electrical connections for the thermostat and the electronics within an enclosure. Replacement filters are sold separately.

Low-Noise Weather-Resistant Enclosure-Cooling Vortex Tubes
Quietly cool electronics inside enclosures while keeping out rain, snow, splashing water, and dirt. These vortex tubes have mufflers on both the hot and cold air outlets to reduce noise. They use compressed air, making them a lower-maintenance choice than electric air conditioners. Adjust the ducting to spread air evenly in your enclosure or to cool specific parts. A filter captures and drains moisture from the air to protect your equipment from water damage.

Low-Noise Weather-Resistant Enclosure-Cooling Vortex Tubes with Thermostats
Quietly cool electronics inside enclosures to your desired temperature while keeping out rain, snow, splashing water, and dirt. After you set the thermostat on these vortex tubes, it works with a solenoid valve to regulate temperature. Cooling turns on and off automatically to cut down on energy use. These vortex tubes have mufflers on both the hot and cold air outlets to reduce noise. Using compressed air, they’re a lower-maintenance choice than electric air conditioners. Adjust the ducting to spread air evenly in your enclosure or to cool specific parts. A filter captures and drains moisture from the air to protect your equipment from water damage.
