Camper Van Ventilation Planner

← All camper van tools

Compare the airflow needed for a target air-change rate with the airflow you expect a fan to deliver.

Your inputs

Average cabin length (ft) Average cabin width (ft) Average cabin height (ft) Share of cabin volume occupied by air (%) Target air changes per hour Rated fan airflow (CFM) Estimated delivered share of rated airflow (%)

Results

Estimated cabin air volume
Airflow for the entered target
Estimated delivered airflow
Estimated air changes per hour
Airflow above or below target

How it works

Multiply length, width, and height by the fraction of the cabin occupied by air. Required CFM is volume × target air changes per hour ÷ 60. Compare that with rated fan airflow adjusted for restrictions.

Reference: ASHRAE’s airflow, volume, and air changes relationship.

What to check before you use the result

Set your own target. This airflow estimate does not establish safe ventilation for a fuel-burning appliance or replace required permanent vents, make-up air, or carbon monoxide protection.
