HAS Mini
A preliminary selection based on the verified platform data and current site inputs.
- Recommended platform
- HAS Mini
- Recommended mode
- Mode 2 · 10 min ON / 10 min OFF
- Preliminary quantity
- 1 preliminary unit
- Installation method
- Place at the documented local delivery point with an unobstructed compact-room circulation path.
- Operating schedule
- 4.0 h/day
KEY ENGINEERING REASON
Mode 2 produces a verified 10 min on / 10 min off pattern with 4 EOG hours per day. Final room suitability and quantity require a verified HAS Mini coverage specification and site circulation review.
Limitations / data still required
- Mode-specific room coverage is not verified in the repository.
- Confirm local circulation, occupancy authorization and the selected EOG lifetime option.
HAS Mini calculation and airflow basis
Detailed engineering interpretation follows the platform’s verified architecture rather than forcing every product into one generic formula.
Define the daily window available for cycling.
Only the documented ON periods consume EOG life.
No room-coverage value is inferred from the duty pattern.
HAS MINI AIRFLOW ARCHITECTURE
ROOM / FCU PLACEMENT→HAS MINI→DOCUMENTED DUTY MODE→LOCAL AIR CIRCULATION
Select a documented duty pattern and verify the local circulation zone.
Use a stable position close to the intended delivery point.
Keep the local delivery and circulation path unobstructed.
Commission one of the documented continuous or intermittent modes.
Confirm occupancy authorization and site circulation before operation.
This is an engineering screening workflow, not a clinical claim. It does not confirm sterilization, pathogen kill, log reduction or safe ozone exposure.
