ADVANTAGES
DUCT-BFC are used to exhaust large amounts of hot or dumpy or greasy smoke (up to 150°C), thanks to the position of the motor housed in a protection hollow inside the fan casing.
INSTALLATION
The airflow is only B type (from impeller to motor) and installation is horizontal or vertical. When the fan is installed in horizontal position and water or condensation is expected, the fan shall be rotated in a way to prevent the hollow to hold back liquids.
CONSTRUCTION
- Casing in hot dip galvanized steel sheet. Flanges according to UNI EN ISO 13351/Tab.1.
- High efficiency impeller with airfoil blades in die cast aluminum alloy, variable pitch angle in still position, hub in die cast aluminum alloy. Balancing according to UNI ISO 21940-11.
- Alternate current asynchronous electric motor, protection IP 55 insulation class F, efficiency EFF.2, S1 service, mounting type B3, construction according to specific directives IEC / EEC (UNEL-MEC).
- Execution 4 (impeller directly coupled to the motor shaft).
