How this tool works
Workshop volume (m³) = length (m) × width (m) × height (m). Size step (mm) = |machine diameter − hose cuff diameter|.
- One machine at a time; no duct pressure-loss calculation.
- Only like-for-like, confirmed airflow measurement bases can be compared.
- All example values are illustrative, not product specifications.
Worked example
A 5 × 3 × 2.4 m room has a volume of 36 m³.
100 mm machine port (od) → 63 mm hose cuff (id). An adaptor with the appropriate 100 mm and 63 mm connections may be needed (37 mm nominal size step). Check mating inside/outside diameters, tolerances, locking fittings and the maker's instructions. Reducing a hose can restrict airflow.
These airflow figures cannot be compared: the measurement basis is different or unconfirmed. Maximum airflow is not the airflow delivered through your installed hose.
Illustrative inputs only; these are not product specifications or an installation recommendation.
