The best fan for your application! DDM range – direct driven fans Direct driven centrifugal fans of DDM range with forward curved impeller directly mounted on the external rotor motor are the ideal solution for your applications in the HVAC business. The fact of manufacturing by ourselves each fan component – the casing, the impeller and motor – enables us to create fans that perfectly meet the requirements of high performances and low power consumptions. The wide range of different versions and motor types allows you to find the fan exactly matching what you really need. You anyway get the generally...

This kind of fans are specially conceived for use in dust-free environments, at temperatures up to +40 °C, or higher on selected models. The performance data have been obtained in a laboratory registered by AMCA for AMCA 210/99 air performance testing. Data are not certified by AMCA. We have the right fan for all your application! Many different sizes, versions and motor types are available in the DDM range. Impeller size (width and diameter) up to 15“ Speed variation either by step-transformers or stepless External rotor motor with integrated thermal protector Fan models suitable for 60 Hz supply...
