  • Expected External Filter Service life of >500-1,000 hours.
  • High volume Recirculation means Cabin filtration cycle is approximately every 1-2 minutes and Filter Element service life of up to 1,000 hours.
  • Cabin pressurisation of >80 pascals.
  • Free flow of ventilation air to offset Co2 is suitable for >3-4 occupants.
