ROOF FAN WITH ABS COWL AND ELECTRONIC MOTOR

MANUFACTURING FEATURES:

• ABS protection cowl easily removable for access to motor and impeller (integrated folding system in models 500, 560 and 630). The ABS cowl is characterized by its toughness, resistance to impacts and is able to withstand extreme ambient temperatures. 100% of the ABS used in the this cowl is recycled.
• The design of the cowl with a rounded shape is specific to minimize the risk of water ingress due to rain.
• Structure in anticorrosive galvanized steel and support frame for adaptation to the roof with anti-bird protection grid.
• High-efficiency backward-curved blade impeller with self-cleaning system. Self-cleaning system. Reinforced polyamide impeller for models 155, 190 and 220. The rest of the models in aluminum.
• EC technology uses integral electronic control to ensure that the motor always runs at optimal load and ensures efficient energy utilization. It incorporates an external rotor EC motor with high efficiency (IE4 for three phase motors and IE5 for single motors) and low noise level. Speed ​​control through a 0-10V or PWM signal. 230V 50/60Hz single-phase power supply for models 155 to 310 and 380-480V 50/60Hz three-phase power supply for sizes from 355 to 630. IP44 and motor class B insulation.
