APPLICATION
Hazardous Location Breather Drains prevent moisture build-up
within hazardous approved enclosures while maintaining enclosure
UL Type rating. Drains are to be used when an enclosure is subject
to fluctuations in temperature which can lead to the formation of
condensation and a subsequent moisture build-up. These drains
allow air within an enclosure to breathe with the surrounding
atmosphere, preventing condensation and any potential damage to
electrical equipment.
FEATURES
• Reduce corrosion that can limit the life of internal electrical and
electronic components
• Prevent condensation when installations are subject to
fluctuations in temperature in hazardous locations
• Effectively drain any water present within the enclosure
• Minimize moisture build-up within the enclosure by allowing air
in the enclosure to breathe with surrounding atmosphere
• Position at the lowest point of an enclosure to ensure optimal
draining of any moisture
• Maintain enclosure’s UL Type rating when properly installed
• Available for Increased Safety (Ex e) and Flameproof (Ex d)
applications
