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.
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.
Replacement filters are sold separately.
