Overview

The Hammond Manufacturing N4X Breather Drain (BDN4XN1) is a pressure compensation plug engineered to protect industrial enclosures from moisture ingress and pressure differentials. Constructed from Durethan BKV 30 (30% glass-filled nylon) with a nitrile O-ring and brass fixing nut, it delivers exceptional durability and corrosion resistance. The unit operates via gravity to drain accumulated liquids while equalizing internal and external air pressure, preventing temperature-induced vacuums that can draw moisture into sensitive electronics. Rated IP66 and NEMA/UL Type 4X, it maintains enclosure integrity in harsh environments. The M20 x 1.5 pipe thread design ensures compatibility with standard enclosures, and the recommended installation of two units in opposite locations optimizes moisture drainage and airflow. Approved for hazardous locations including CSA Class I, Zone 1, Ex e II and Class I Division 2 Groups ABCD, it withstands operating temperatures from -50°C to +85°C. Ideal for control panels, junction boxes, and outdoor electrical enclosures where condensation and pressure fluctuations pose risks to system reliability.
