High Altitude Ventilation


  • Are there different recommendations for high altitude ventilation?
  • Is more CFM needed in high altitudes?
  • What are the high altitude ventilation recommendations?


Ventilation systems are less effective at altitudes above 5,000'. At these altitudes, you should estimate a 20%-25% reduction in CFM performance. Using a higher CFM blower and increasing the duct size is recommended.

For further ventilation information, refer to the Wolf Design Guide.
