BACKWARD CENTRIFUGAL FAN, FOR CLEAN OR SLIGHTLY DUSTY AIR

MANUFACTURING FEATURES

• Medium pressure centrifugal fan with direct coupling.
• Reinforced housing made of carbon laminated steel, protected against corrosion by powder coating polyester resin RAL 5010. Finish C3.
• Casing fully latched and adjustable.
• Self-cleaning impeller and reinforced impeller with high-performance backward (reaction) blades made of carbon laminated steel dynamically balanced to minimize noise and vibrations. Black painted RAL 9005
• The size of the centrifugal impeller and casing is larger than a NIMUS , which increases the performance of the unit.
• Squirrel cage standardized asynchronous IEC motor with IP-55 protection and class F electrical insulation. Standard voltages 230/400V 50Hz for three-phase motors up to 4kW and 400/690V 50Hz for higher powers.
• Motor with feet (B3) supported on motor support foot.
• Models of size 500 and above are supplied with a front support foot, for the other models the front support foot is optional.
• Maximum working temperature in continuous: air transported: 130ºC, environment: 60ºC.

• Available positions (to be indicated in case of order): LG270, LG0, LG45, LG90, LG135, LG180, LG225, LG315, RD0, RD45, RD90, RD135, RD180, RD225, RD270, RD315.
