VENTILATION BOX WITH BACKWARD IMPELLER
MANUFACTURING FEATURES:
•Ventilation box with 30 mm aluminum profile structure, nylon corners, galvanized sandwich panels with internal insulation rockwool (25mm thickness) class A1 (non-combustible) of 90kg/m3 density. All panels are equipped with "fastening system" for the quick assembly and disassembly whenever required, either for cleaning, maintenance or exchanging of panels.
• Centrifugal fan with motor coupled directly to the impeller, plugfan type.
• Circular inlet to facilitate duct connection. Open outlet.
• Models with AC motor inside the air flow. Standard asynchronous squirrel cage motor with IP-55 protection and Class F insulation. Standard voltages of 230V 50Hz for single phase motors, 230/400V 50Hz for three phase motors up to 4kW and 400/690V 50Hz for higher powers 1 speed and 400V for 2 speed motors.
•Backward curved single inlet impeller of high performance with self-cleaning system made of steel. Balanced statically and dynamically at origin.
• Exchangeable panels.
APPLICATIONS:
Designed for inline installation, they are suitable for:
• Air renewal in buildings and industries.
• Smoke extraction.
• Maximum working temperature (ambient and airflow): 50ºC for single phase motors and 60ºC for three phase motors.
