What are ATEX Breather & Drain Plugs?
ATEX Breather & Drain Plugs are certified enclosure accessories designed for hazardous area electrical equipment. They allow controlled breathing and draining inside Ex enclosures, junction boxes, control panels, terminal boxes, instruments, and field equipment.
A breather plug helps balance pressure inside the enclosure when temperature changes occur. A drain plug helps release accumulated moisture or condensation from the enclosure. In outdoor and humid environments, this function is important because trapped moisture can damage terminals, wiring, components, and insulation.
These plugs help to:
- Reduce condensation inside Hazardous Area enclosures
- Drain collected moisture from certified equipment
- Support Explosion Proof and Flame Proof enclosure safety
- Protect terminals, wiring, and components from water damage
- Improve enclosure life in outdoor and humid areas
- Support Zone 1, Zone 2, Zone 21, and Zone 22 installations
- Help maintain IP protection when selected correctly
- Support ATEX and IECEx compliance requirements
