LSM QCabAir® (pat. pend.)- ISO 23875 solution for CAT 854k Wheel Dozer

LSM Technologies Engineering Team designs LSM QCabAir® (pat.pend.) Cabin Pressurisation / Filtration Commixing Plenum Technology to exceed ISO 23875 compliance and extend HVAC service life. The QCabAir® specifically compliments Caterpillar machines providing the highest protection for Operators.


  • LSM QCabAir® (pat.pend.) Commixing Plenum Technology for Cabin Pressurisation / Filtration provides:

  • Specifically designed and engineered for machine Cabin with as- built drawing by LSM Engineering Team - also means Kit can be self- installed
  • Pre- assembled and certified and DOP tested to EN1822 / ISO 29463 for HEPA Filters classed as H13 / ISO 35H provides time and costs savings with quick / easy commissioning on machine
  • Mounting and ducting design considers other OH&S needs such as Operator visibilityROP's / FOP's integrity,  and to handle machine inertia / vibration.
  • Ducting of both commixed External (ambient temperature) and Recirculation Air directly over the HVAC evaporator ensures more efficient HVAC operation and balanced dynamic loading.
  • Stainless-Steel construction- no corrosion contamination (rust) so as the QCabAir® Plenum will last virtually forever
  • Protection of the Cabin and Operator / Occupants exceeds ISO 23875 compliance.
  • Operator comfort has been maximised with better thermal dynamics.
  • Easy access for Filter Element for replacement.
  • Extended length Filtration Elements providing better air flow and also less frequency for replacement. 
  • 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 / 2,000 hours.
