DIRECT DRIVEN SCREW
Direct Driven Screw

 

In this case direct-driven means that the drive power of the motor is transmitted to the airend directly - with no loss owing to V-belt or gear drive. It is performed with a flexible coupling between the motor and the airend.

The efficiency of this drive type is approx. 99.9% and is hence significantly higher than with conventional drives.

The permanently operating compressors of the direct series thus deliver more compressed air using even less electrical energy, around the clock.

The direct series is designed so that it can be operated extremely efficiently in each kW class owing to its unique design concept. This means it can be used in a wide variety of applications.  In combination with the speed-controlled variable, it becomes unbeatable. Both plants are identical in design, except that the variable is equipped with a frequency converter.
