Frequently Asked Questions

Q: What's the difference between the SGE 400/3 and the SGE 400/3BB? A: The "BB" designation means butyl rubber face seal. Butyl rubber provides superior chemical resistance, especially against mustard gas and other blister agents. The standard SGE 400/3 uses silicone, which is more comfortable but less resistant to certain chemical agents.

Q: What threats does this mask protect against? A: The SGE 400/3BB with the included CBRN filter protects against chemical warfare agents (sarin, mustard gas, VX), biological agents (anthrax, smallpox), radioactive particles, tear gas (CS/CN), industrial chemicals, and toxic vapors.

Q: What does A2B2E2K1 + P3 mean? A: This is the European filter classification. A2 = organic gases, B2 = inorganic gases, E2 = acidic gases, K1 = ammonia, P3 = highest particulate protection (99.99%). This filter covers the broadest range of threats.

Q: How long does the filter last? A: The sealed filter has a 5-year shelf life. Once opened and in use, it provides up to 24 hours of active filtration depending on contamination levels.

Q: Can I mount the filter on either side? A: Yes. The mask has three 40mm NATO ports—left, right, and center—so you can mount the filter on your preferred side or use center-mount for powered respirators.
