Focus on Balanced Mid-High Flow M5 Model HA-5A-4

The HA waterproof breather vent valve is a high-performance enclosure protection component designed for industrial and electronic systems exposed to challenging environments.
It combines waterproof protection, air permeability, and pressure regulation in a single compact structure. This ensures that sealed enclosures maintain stable internal conditions regardless of external environmental changes.
By preventing condensation, reducing pressure stress, and blocking contaminants, the vent valve significantly improves equipment reliability and operational safety.
Its wide compatibility with different thread sizes allows flexible integration across various industrial applications, including telecommunications, automotive electronics, energy systems, and outdoor installations.

Product Advantages

Focus on Balanced Mid-High Flow M5 Model HA-5A-4 9

Broadly Compatible Flow

At 9ml/min, the airflow covers the vast majority of outdoor enclosures from 10L to 60L—whether PV inverter integrated boxes or base station main equipment cooling cavities—delivering just the right pressure release, avoiding membrane fatigue from excess flow or cabinet bulging from insufficient flow.

Optimized Human-Machine Interface

With 11mm body diameter and 11.5mm wrench size, the top features a cross or hex socket drive for quick tool-based installation/removal without specialty wrenches, facilitating field maintenance and inspection.

Enhanced Thread Strength

With 5.8mm thread length providing ≥7 engaged threads, aluminum enclosures achieve ≥20N·m torque resistance, effectively preventing valve rotation loosening from high winds or cable tension.

Comprehensive Environmental Adaptability

Triple-certified for -50°C~150°C, IP68, and -120mbar water entry pressure, the HA-5A-4 performs reliably whether under the Tibetan Plateau's strong UV, South China Sea islands' high heat/humidity, or Northeast China's severe winter cold.
