HAS Pro
A preliminary selection based on the verified platform data and current site inputs.
- Recommended platform
- HAS Pro
- Recommended mode
- Level 2 · 200 m³/h · mode confirmation required
- Preliminary quantity
- 3 preliminary airflow zones
- Installation method
- Allocate a clear intake and discharge position to each preliminary airflow zone and commission each zone independently.
- Operating schedule
- 24.0 h/day
KEY ENGINEERING REASON
3 preliminary airflow zones are indicated by the entered 3 zone plan and 400 m³/h airflow. This is an airflow review only; final HAS Pro sizing requires verified coverage and site distribution data.
Limitations / data still required
- The repository does not provide a verified area or volume coverage rating.
- Confirm treatment mode, zone airflow, occupancy procedure and final unit quantity with BES Engineering.
HAS Pro calculation and airflow basis
Detailed engineering interpretation follows the platform’s verified architecture rather than forcing every product into one generic formula.
Use only the verified 100, 200 and 400 m³/h fan levels.
Partitions and return paths define the preliminary zone count.
No area or volume rating is invented for final sizing.
HAS PRO AIRFLOW ARCHITECTURE
CENTRAL / ZONE RETURNS→HAS PRO→100 / 200 / 400 m³/h→MULTIPLE ENGINEERED ZONES
Review airflow and zoning without assigning an unverified room-coverage rating.
Survey partitions, doors, intake paths and discharge paths.
Allocate one clear position to each preliminary airflow zone.
Maintain the documented inlet and side clearances.
Confirm mode, airflow and final quantity with BES Engineering.
This is an engineering screening workflow, not a clinical claim. It does not confirm sterilization, pathogen kill, log reduction or safe ozone exposure.
