FAQs

Q1: How long do NBC filtration systems last?

A: Premium NBC systems can last 500–1000 hours, while budget filters typically require replacement after 200–300 hours. Lifespan depends on usage, environment, and exposure to agents.

Q2: Are budget NBC filters safe to use?

A: Yes, budget filters are safe for low-risk environments. However, for high chemical or biological threats, premium systems offer stronger protection and higher reliability.

Q3: What is the ideal airflow for an NBC bunker?

A: The standard requirement is 10–15 CFM per person, plus an additional 20% capacity for surge. This ensures proper ventilation and maintains safe internal pressure.

Q4: Why is overpressure important in NBC bunkers?

A: Overpressure of around 250–300 Pa prevents contaminated air from entering the bunker. It acts as a protective barrier, ensuring only filtered air circulates inside.

Q5: Why choose premium NBC systems despite higher cost?

A: Premium systems provide longer lifespan, superior filtration, and lower failure risk. Over time, they reduce maintenance and replacement costs, delivering better ROI.
