Collective Isolation

The Alaska Structures Negative Pressure Isolation System includes 3 components: a Filtration System that maintains negative pressure within the shelter, an Alarm System that monitors pressure and signals a loss of pressure, and a shelter partition for creating an Anteroom entrance to the isolation area.

||  Features and Benefits

  • The NPI system controls three elements of indoor air quality: particles, biological and gas phase volatile organic compounds (VOCs)
  • It includes a high efficiency germicidal pre-filter, sterile sweep ultraviolet light (UVC) and a final HEPA filter
  • Power supply, 220 volt, 50 Hz -Includes a manual on/off switch with air proving switch to shut down the filter when no airflow is present
  • When functioning in combination with the Alaska Environmental Control Unit (ECU) it provides a minimum of 20 air exchanges per hour
  • Cleans 2200 CFM of return air with a non-ionising, polarised media electronic air cleaner coupled with a UVC emitter
  • HEPA filter efficiency is 99.97% for particles 0.3 microns and greater
  • Includes differential pressure gauge to monitor filter status
  • Provides a negative static pressure in inches of water gauge (SPWG) in the range of (.01-.04 in. SPWG) within a 20 ft x 32.5 ft shelter
  • Alarm system incorporates an ultra-sensitive pressure transducer to measure pressures ranging from .01-.04 in. SPWG
  • The alarm system provides visual alarm and audible alarm along with a digital indication of pressure and alarm status
  • System may be re-configured for providing positive pressure clean environment within the shelter, without requiring any additional items
