50 Hz
LONG CASE FAN WITH BACKWARD IMPELLER
MANUFACTURING FEATURES:
• Reinforced fan casing manufactured in rolling steel sheet. Polyester powder finishing coat. Housing with motor access door.
• High efficiency backward impeller with self-cleaning system in steel sheet, balanced static and dynamically in origin.High efficiency impeller with built-in diffuser, which eliminates the need to use a scroll or spiral casing to obtain performance.
• 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.
• Maximum working temperature 60ºC.
APPLICATIONS:
Designed for inline installation, they are suitable for:
• Air renewal in buildings and industries.
• Smoke extraction.
