HEPA H13 CBRN Air Filtration Installation in Bozeman

Common Challenges

• Contaminated air seeps through cracks without positive pressure

  Bunkers without overpressure blowers let chemical vapors and airborne particles infiltrate through ventilation gaps and foundation cracks during events.

• HEPA filters clog fast in high-particle environments

  Single-stage filtration systems fail when particle loads spike during fallout, leaving occupants exposed to contaminated air within hours.

• Freeze-thaw cycles crack intake vents in Bozeman winters

  Heavy winter snow and freeze-thaw cycles damage uninsulated air intake systems, creating infiltration points for contaminated air.

How We Help

• HEPA H13 filters capture 99.97% of particles down to 0.3 microns

  Multi-stage filter banks with HEPA H13 and activated carbon remove airborne particles, biological agents, and chemical vapors before air enters the bunker.

• Overpressure blowers maintain positive pressure to block infiltration

  Blower systems sized for bunker volume create positive pressure that prevents contaminated air from seeping through cracks or ventilation gaps.

• Filter change protocols allow safe replacement during events

  Isolation valves and pre-filter stages let you swap HEPA and carbon filters without exposing occupants to contaminated air.

• Systems tested for airflow and pressure before handoff

  All NBC filtration installations are verified for CFM delivery and positive pressure maintenance under load before final acceptance.

• Insulated intake vents withstand Bozeman freeze-thaw cycles

  Intake systems designed for heavy winter snow and freeze-thaw exposure prevent vent damage that compromises filtration integrity.
