Enclosure Ventilators

Enclosure ventilators (also called breather vents or pressure‑equalizing vents) allow air exchange between the inside and outside of electrical cabinets or control boxes. They prevent condensation, reduce internal pressure buildup, and help temperature equilibrium.

Primary Functions & Design Criteria

• Condensation control: By allowing controlled airflow, ventilators reduce moisture accumulation on internal surfaces.
• Pressure equalization: Mitigate differential pressure caused by temperature swings or altitude changes.
• Made from polycarbonate or ABS plastic
• Two sizes: For 60mm or 80mm fan
