Evaluates the ability to facilitate air exchange while maintaining pressure balance. Use specialized airflow measurement equipment to assess the smoothness of gas passage through the vent. Ensure there is no excessive resistance that could hinder pressure regulation.

Focuses on waterproof and dustproof capabilities. Simulate harsh environmental conditions such as high humidity, spray, or dusty settings to test the vent's barrier function.

After exposure, inspect the interior of the vent and associated equipment for signs of moisture intrusion or dust accumulation.

A qualified vent should effectively block external contaminants while retaining ventilation functionality, ensuring the protected equipment remains free from damage caused by water or particles.

Indispensable given the SUS316L material's key advantage. Expose the vent to corrosive environments that mimic real-world applications, such as:

After a specified exposure period, examine the vent's surface for rust, pitting, or material degradation. SUS316L's inherent corrosion resistance should prevent visible damage, confirming the material's integrity and long-term reliability in harsh conditions.

Ensures the vent maintains airtightness when not in active ventilation. Use pressure testing methods to detect potential leaks.

The vent should form a secure seal to prevent unintended entry of liquids or contaminants while allowing controlled airflow when pressure differentials occur.
