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.
Washdown Enclosure-Cooling Vortex Tubes

Suitable for washdown applications, these vortex tubes are NEMA rated to resist washdowns. 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.
NEMA 4X rated vortex tubes resist dirt, washdowns, and corrosion.
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 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.

Hazardous Location Enclosure-Cooling Vortex Tubes

UL classified for hazardous locations, these vortex tubes convert compressed air into a stream of cold air to keep electronics within enclosures from overheating while also keeping dust and other contaminants out. They chill compressed air by 50° F or more. These vortex tubes have a check valve that seals the air outlet when the unit is not in use, allowing the enclosure to be pressurized. All include a ducting kit to distribute cool air throughout the enclosure.
Vortex tubes with a cooling capacity of 5,000 Btu/hr. have dual air outlets that release two cold air streams. They’re good for cooling down large enclosures and electronics that generate a lot of heat. You can direct the air streams separately to target specific electronics. These vortex tubes take up more space inside of enclosures than those with a lower cooling capacity.
