![]() Impeller with forward curved blades of galvanized steel plate, directly mounted on a brushless, permanent magnets, DC-external rotor motor, no transmission losses, dynamically balanced according to ISO 1940. Scroll casing made of galvanized steel (EN 10142), assembled through a high technology roller-locked seaming. High efficiency direct driven centrifugal fanÄouble width, double inlet (DWDI), direct drive. Simple installation due to plug and play.No obstruction of intake due to build-on control unit - less aerodynamic losses.New compact and streamlined motor design.even in partial-load operation! The EC-motor therefore uses less power than the AC motor under all operating conditions and has a significantly higher level of drive system (motor and control) efficiency. Important: This applies for all speeds, i.e. ![]() The EC-motor operates without slip losses and thus consumes significantly less power than conventional AC motors. ![]()
