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 4 rated vortex tubes resist dirt and washdowns.
NEMA 4X rated vortex tubes resist dirt, washdowns, and corrosion.
Replacement filters are sold separately.
