Technical Data
AC, EC and IEC motor models are all available in sound attenuating versions. IEC Motor Variations (DVWN) can be operated up to 120 °C as the motor is outside of the airstream. The fans are driven by IEC three phase motors and up to size 450 are suitable for voltage control. From size 500 the fans are controllable with a frequency converter. The motor carrier cage is a plastic coated round wheel and has been created with bird and contact protection.
