Key features:

1.Aluminum airfoil propeller: move high volumes of air with maximum thrust and maximum efficiency.
2.Galvanized casing: continuously welded to prevent air leakage.
3.Motor plate: securely welded to fan inner tube to improve rigidity and prevent vibration.
4.Silencers: available in two options short (one diameter length) and long (two diameter length).
5.Direction vanes: available on select models to direct airflow.
6.Smoke extraction: 300â°c for 2 hours (f300 certificate 370-cpr-1745) and 400â°c for 2 hours (f400
Certificate 370-cpr-1848) available on select models. Tested and certified in accordance with
En12101-3:2002
7.Iec rated motors: 50 hz or 60 hz motors available, in single or two speed, vfd rated, and eff2 or
Ie2 efficiency
8.Amca air and sound certified

Key considerations:
1.Standards: apply relevant codes such as nfpa, ibc, ashrae, and european standards
2.Required air changes: optimize air flow for normal and fire modes
3.Sound: reduce sound levels to acceptable limits for tenants
4.Control strategy and sequencing: define sensor to fan correlation and system response
5.Accessibility and aesthetics: advise on placement of ramps, wall openings, and pedestrian exits
6.Greenpark components: reduce cost and optimize safety with selection and placement

Typical ventilation applications area include:
1.Enclosed / basement air and smoke ventilation
2.Enclosed / basement car park air and smoke ventilation
3.Tunnel ventilation
4.Linear air ventilation, in industries etc
5.Ductless ventilation system
