Direct drive via elastic coupling between the drive motor and the compressor stage
Suitable for compressing purified gas
Outstanding operating reliability
Dynamic oil film between the rotor vanes and the inner wall of the compressor housing
Low rpm and self-centering rotor
The gas flows through the suction line to the compressor stage. Here it is compressed as a result of the increasingly smaller volumes of the compression chambers. The compressed gas exits from a compression fitting on the compression stage through a check valve and enters the compression-side piping system.
The compressor is cooled by a separate cooling air blower in the acoustic hood. The intake cooling air flows through the acoustic hood from the bottom to the top and is discharged to the outside through the discharge air hood.
The compressor is driven by a built-in electrical motor via V-belt.
Safety Equipment and Display
Check valve on the pressure side
Contact pressure gauge to monitor the compressor pressure, with two electric switching contacts, measuring range: 0 to 4.0 bar
Contact thermometer to monitor the outlet temperature, with two switching contacts, measuring range: 0 to 300 °C
Emergency stop switch to shut off the compressor in emergency situations
Terminal box (Exe/Exi) for wiring of electrical components
Parts & Service
Service and maintenance are costly and time consuming necessities. To keep your costs down we offer hands-on workshops for your technicians to empower them to carry out service fast and efficiently at your plant. Successful attendance of our in-depth trainings for ATEX machines is rewarded with a certificate. If your machine actually breaks down we provide fast and efficient support from the factory.
