50 Hz
CENTRIFUGAL FAN IN STEEL CASING WITH ELECTRIC MOTOR EEC
MANUFACTURING FEATURES
·Casing made of polymer coated steel, totally air tightness for outdoor installation.
·EC motors enable integration of several fans into a unified networks and their centralized control.
·Backward impeller with high efficient electronically commutated (EC) direct current motor with external rotor. Turbine is dynamically balanced while assembly.
·Motors are equipped with ball bearings for longer service life of the fan (40.000 hours). IP 44 motor protection index.
APPLICATIONS
·Designed for supply and exhaust ventilation and air conditioning systems for various premises requiring cost-effective solution and controllable ventilation.
·Inside or outside duct installation.
·EC motors reduce energy demand by about 35% and ensure high aerodynamic performance and low noise level. Specially designed for ventilation of public premises such as:
banks
supermarkets
restaurants
hotels
·Its use is also contemplated in installations close to residential buildings and for domestic applications, such as the ventilation of private swimming pools.
