CBRN Air Filtration Installation in Havre, Montana

Common Challenges

• Contaminated air seeps through cracks without positive pressure

  Bunkers without overpressure blowers let chemical vapors and radioactive particles infiltrate through door seals and ventilation gaps during events.

• DIY filters fail to capture nerve agents or pathogens

  Hardware store HEPA filters lack activated carbon banks needed to remove chemical vapors, leaving families exposed to airborne toxins.

• Extreme cold winters stress blower motors and seals

  Havre's subzero temperatures cause standard blower motors to fail and door seals to crack, compromising positive pressure when it matters most.

How We Help

• HEPA H13 filters capture 99.97% of airborne particles

  Filter banks remove radioactive dust, biological spores, and particulates down to 0.3 microns, verified through airflow testing before handoff.

• Activated carbon banks remove chemical vapors

  Multi-stage carbon filtration strips nerve agents, industrial chemicals, and toxic gases from incoming air before it reaches living spaces.

• Overpressure blowers maintain positive pressure

  Variable-speed blowers keep bunker pressure 0.5 inches water column above outside air, preventing contaminated air infiltration through any opening.

• Filter change protocols enable safe replacement during events

  Sealed filter housings with glove ports let you swap HEPA and carbon filters without exposing interior air to outside contaminants.

• Cold-rated blowers sized for plains climate

  Motors and seals rated to -40°F maintain airflow and pressure during Havre's extreme cold winters without performance loss.
