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 with Thermostats
Set the thermostat and these vortex tubes switch on only when needed. Suitable for washdown applications, they 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 4 rated vortex tubes resist dirt and washdowns.
NEMA 4X rated vortex tubes resist dirt, washdowns, and corrosion.
Replacement filters are sold separately.
